Start with the seller, not the price
The cheapest listing is rarely the safest one. Before you pay anything, look at how long the vendor has been trading and whether their store page shows real reviews.
Insist on escrow
With escrow your money sits with BebaMart until you confirm the item arrived as described. A seller who refuses escrow is telling you something.
What escrow actually covers
It covers non-delivery and items that arrive materially different from the listing.
Check the warranty story
Grey imports often carry no local warranty. Ask who services the item if it fails in month three.
