To those who trade with people in the USA and have them ship at their border mail service in the US (Kinek and others), what do you show at customs when you drive back into Canada and need to pay taxes and duty? It's not like you bought the beer so you don't have receipts or invoices to show... Last time I printed the prices of each beer when they were released at the brewery, but ever run into problems using that strategy? Thanks!
If you're just going over for a day trip and think you will get pulled over I just did exactly what you did. Printed up the prices that were available online and that seemed to be fine. I actually did get pulled over the last time with those in hand and the guy barely looked at them and just took my word the $$ amount I was claiming. also, this http://www.bartowel.com/board/viewtopic.php?t=9786
whoever buys the beer scans and emails you a receipt. If a company sends you a box, they of course will have a receipt in the box. The border is cracking down on seeing receipts.
