Hi guys !
Just joined and loving it.
What the deal with brining stuff back ?
We are taking 4 suitcases, and I was thinking of bringing some stuff home like Trainers, Clothes, maybe makeup my wife will buy and disney stuff.
(no alcohol or smoking itmes at all )
One lady in travel agents mentioned we might get hassle if we took 4 bags, and brought 5 bags back on return flight, and that there a limit to how many $$ worth of goodies you can bring back ?

Come'on its my first time in the US !!!

When you get back to the UK, you will get through UK Customs.
You have a £390 allowance per adult passenger (children might get a lower allowance, check with HM Revenue services)
This means that you are allowed to bring back goods with a total value less than £390 per adult passenger.
If you exceed this limit, you will have to pay duties (the same taxes you would pay on the value of the item if you had bought it in the UK)
Meaning that if you bring back £500 you'll need to pay a duty of 20% = £100
It's a good idea to keep all of your receipts to prove the value of the items you bring back
now that was for the letter of the law
what comes next is up to you
when you come back you have 2 options : declare or not to declare.
If you declare your goods and exceed the allowance, you have to pay the duties
If you don't declare it will depend if you get pulled out or not.
Obviously it's easier to get pulled out for a search if you have more suitcases than you have party members.
But going one way with 4 suitcases and back with 5 does not make a difference. The Customs officer doesn't know you have one more suitcase (and as a matter of fact, many people here come back with an extra suitcase)
If you get pulled out of the line and searched, then you're in trouble. Since you'll have to pay the duties and a fine (hefty)
There is one thing you should consider though (and I'm not talking about bending the rules, just using common sense) if you buy clothes, don't make it obvious that it's been bought abroad (take of price tags and such things). Wear the newest items for the trip and keep the "used" stuff in the suitcase (trainers for example).
Only buy a quantity that's for your own use. Do not buy the same item 10 times even if it sounds a good gift idea for your 10 siblings.
If you do get pulled at customs, what will be under scrutiny are the items that are visibly souvenirs, crafts, perfumes, alcohol (special allowance for alcohol and tobacco)
If you have less than £390 worth of souvenirs for each adult passenger, then you don't need to worry. Keep the receipts so you can prove you have less than the allowance, just in case.
