I have been sending BB boxes through LBC for almost 15 years. First bit of advice, ignore the person you spoke to at LBC. I have never asked or been told that I am limited to 12 of anything. But, if nothing else, say you are sending 36 shirts. List as 12 Boys shirts, 12 Mens shirts. 12 womens shirts. See what I mean? The do not check your boxes anyway. I have sent many things that I either did not list or listed incorrectly. For chocolates, the best deal is the big bag at Costco. I don't know how you can 15 of those in a single bb box. I have sent computers, laptops, cash, jewelry, etc. and never had a problem. If you list them they will want to charge you extra. Bottom line is no one is going to open your box and search it.
