@luckycat872 fingers crossed for next time - at least you can learn from our mistakes
In response to your customs question, I was charged for two items last round, uploaded the receipts and was reimbursed, although I do make sure I choose a lower value item if allowed when it's coming from overseas
I'm on round 3 of A**r and getting the hang of it now I think. When I first did it I was choosing stuff I wanted or would be suitable for gifts if I was able to pick from a site, now I'm buying the most expensive thing within budget from any site that comes up with a good returns policy so at least I know I'm earning a certain amount and can spend it on something I really want
I also pay for fast delivery so I can get the task over and done with as quickly as possible.
Luckily this time I only had one item not load so purchased 6 and all were UK sites with 5 offering returns so hopefully I'll earn a bit and it'll be straight forward (famous last words)
