I switched to Canadian currency in my two shops a couple of weeks ago and I have been attracting more Canadian sales, especially at my vintage shop
http://www.TipsyTimeMachine.etsy.com But I do wonder if the irregular (not rounded off) numbers are turning off American buyers. Jewellery is a very competitive category, most of my pendants used to be $25 US, but now that I've set them at $25 CAD, that does raise the price.
So I would like to hear from those who list in their own currency (any country), as to how this has affected their sales (good or bad or just different). If you're an American, it would be great to hear if these irregular numbers ($26.21 instead of $26) are a turn off for you.
