• Payment Conditions

All the prices in the store are in Euro currency (€, EUR).

The primary payment method in the store is PayPal. With PayPal, you can make payments by using all major credit or debit cards or by using your PayPal balance. We accept bank transfer payments - see bellow for details.

How do I order with PayPal?

You don't have to register on our site. Just choose your product and select an option from the drop-down menu (if any). Then, click the "Add To Cart" button. The system will redirect you to the PayPal shopping cart page. Once there, you can proceed to the payment or return to the shop by clicking the "Continue Shopping" button and add other product(s) to the cart. You can remove products from the cart by clicking the "Remove" link next to a product. Once finished adding products, you shall proceed to the payment. You have two options (may be different in some countries):

Payment using your PayPal account

1. You can pay using your existing PayPal account. To do this, click the "Check out with PayPal" button , login to your PayPal account and confirm your order. After a successful payment, you'll receive a payment confirmation to your PayPal registration e-mail. That's all.

Card payments - Payment without PayPal account
2. You can pay without a PayPal account using your credit/debit card. To do this, click the grey button with "Check Out" label and a "Pay without a PayPal account" statement under the button. You will be redirected to a secure PayPal page, where you have to fill all your data and finish the payment by clicking the PAY NOW button at the bottom of the page. After a successful payment, you'll receive a payment confirmation to your e-mail. That's all.

Bank Transfer Payments

We accept direct bank transfers to our bank account. There is NO a possibility to place an order with this type of payment on the website! If you want to pay by bank wire, please contact us and we will give you detailed instructions on how to proceed with your purchase.

Bank transfer payments should be made to the following recipient:
Account holder name: Linoart Ltd.
Bank: UniCredit Bulbank AD
Bank address: Sv. Nedelia sq., Sofia 1000, Bulgaria
IBAN: BG03 UNCR 9660 1029 1162 09

You don't need a bank account to make a transfer to a bank account. You can do this using your bank card (debit or credit) and a web-based platform for bank account payments. There are dozens of them on the Internet, the most known is maybe (former TrasferWise).

PayPal secure payments

Why PayPal as a primary payment method? Because checking-out with PayPal is fast and secure, and because PayPal is a world leader in online payments, so no need to explain to everybody what this is. Another great feature of PayPal is that we can accept all major credit/debit card payments without having to pay enormous amounts of money for supporting our-own payment gateway. And this is good for you, our customers, because this keeps the prices low.

EU Shipping Charges

The shipping charge to the EU countries is set by our system according to the pricing policy at Speedy/DPD - our main shipping company for EU orders.

Shipping to Cyprus, Ireland and Malta is with TNT - sorry, DPD does not deliver to these countries.

The default shipping charges, displayed on our website are for a parcel with total weight of up to 3 kg. If your order exceeds this weight, additional shipping charges may apply. A single VLF detector with a medium-sized coil, batteries, the cartoon and all the accessories in the kit weights approximately 2.9 kg without the wireless headphones and up to 3.2 kg with the wireless headphones included.

Insured Courier Shipments

If your order is shipped with a courier service (DPD, DHL, TNT), the parcel is shipped with insurance at the full amount you've paid.

Please check the goods for any defects and/or injuries and missing components caused by the transportation BEFORE the courier leaves! If you find something wrong - broken or missing part, you should ask the courier to make a document (protocol) about all injuries or missing parts. With this documents you could ask payment of a compensation and prove any complaint.

Low-cost orders

Low-cost orders (orders with total value under 50 EUR incl. the shipping charge) are shipped with the Bulgarian posts, with priority mail, signed for.

Non-EU and Worldwide Shipping

If you are outside the European Union, we will ship your order with DHL or FedEx/TNT. Our system automatically calculates the shipping charge - you can see the amount above the PayPal button. The shipping charge includes full insurance for your purchase.

The shipping to countries outside the EU requires some additional export procedures and papers that take up to 3 days. So your order is not shipped immediately after we receive the payment, but right after we prepare all the papers needed and the customs authorities release the parcel for export.

WARNING! If you are outside the EU, you get a lower price without VAT, but you'll probably have to pay an import tax and/or VAT in your country. In some countries you'll have to pay both. So please make a research about customs duties in your country and be prepared to pass an import procedure.

Other Shipping Options

In this case we will refund the order value minus the shipping charge and minus all the following expenses we will have to pay - the return shipping charge; parcel storage tax in your country (if any); import/export papers handling taxes (if any); import duties in Bulgaria (when the parcel is imported back) and import procedure tax in our country.
