This site already comes with a travel store with items from amazon.com. To give users from other countries the chance to safe on shipping, I decided, well, I go through the tendious task and do the same for other countries. See, the problem with amazon is, if you want to use their affiliate program and target different countries, you need to sign up with each countries' program. And start from the scratch building your links.

I started with the US shop, I already have and thought, hm, I could easily just copy the categories and fill with the same items. Wrong! Not only that they each sport a different category system, they also contain very different items. At least if you go for the non-books section.

I haven't decided yet if I just forget the whole idea or set up country targeted shop with reduced items.

It's sometimes a little bit tricky to only get the items you look for:
If you select First aid and Safety as your keywords (in the UK ashop) one of the first item is a vibrator. Could be considered a First aid item I guess, but would not be the first one I think of.

What are your experience with setting up an amazon store? If you have tips, please leave a comment.
