If you buy several lots from different brands, I will combine delivery. If you overpay for delivery, I will refund you the price that you overpaid more than the actual delivery cost!
The cost of delivery depends on the weight of the parcel.
Approximate delivery cost (the price depends on the country of the buyer's location for large parcels)
0-250 grams - 10 dollars
250-500 grams - 15 dollars
0.5 - 1 kilogram USD 25-28
1 - 2 kilograms 35-38 dollars.
I try to split large parcels into several sent so that it reaches the buyer better and faster.
Radio lamps and indicators are sent by the Ukrainian state postal service, Ukrposhta
(at this time it works very well and without failures, your purchases will be delivered without problems, all track numbers are tracked the entire way of the shipment and you can see it online in all tracking services)
