its less of a success rate if you send more then one. Cause it will have a number on the item. If you send (250) with 2 its gonna say 2 and they wont take it. But if you just put 1 then it shows no other number and they think its 250 when they take it out.
This works amazing man and i wish i could +rep you. Ive made over 500g so far. Thanks much.
