I too am an Amazon fan. If you need to return an item, you call..get a prepaid ticket...box it and drop it at the post office. 2 days after received...money returned.
The only thing I want to add is..are you close enough to the border to make a drive down conveniently? If so...go Googling and find one of the many, many 'receivers'..I use Kinek...they will accept any package and hold it for you at a fee of 4 or 5 bux. You go down and collect it. You avoid shipping charges and usually are not dinged at the border on duty. I mean..if you rack up a huge dollar figure, you might not get by, but I have yet to pay duty even up to $1,000.00.
Shipping fees can and will really add up, so be aware. You don't always see the actual final tally until just before hitting the 'Buy Now' toggle. Do NOT get sucked into Prime on Amazon.com. You will get the free shipping but all the other stuff like movies and books? nu uh...you are NOT in the US.
Do price comparisons..even on Amazon. ca and Amazon.com. They are NOT the same and you might be super shocked at the pricing difference on some items. ie: I bought an item that was $18.00 on .Com...was $110 on .Ca (not an RV item)
If you are comfortable, Pay Pal is good...but I use a charge card with Amazon.
