I have active account based in the UK but domt really know if it is worth it or not these days to work on it
Yes it’s still worth it with €5k and an active UK account if you avoid big China orders and instead use it for 1 small own brand product from a UK supplier plus 2-3 small wholesale tests to find a winner fast
Is it to build a PL brand? If yes, then the answer would probably be NO, not enough.
You have to do the calculation based on the product type, pricing, demand, amazon fees, logistics, storage, marketing etc. If you dont, it will be a guess!
