Maybe Bitcoin fits better for online stores, not physical ones, but I support such initiatives. It's difficult to expect that significant part of users will pay in Bitcoin, but I'm sure that you'll find people who will appreciate that you give such option.
But I always had question about physical stores and Bitcoin. What they are doing when it takes hours to confirm transaction?
If you damaged something or already used it up, that obviously doesn't apply but for tech stuff you just keep the receipt and return the product if you don't like it.
In this scenario, I could definitely buy something with bitcoin and profit from refund it
It's like shorting/selling bitcoin to fiat and if the price goes up, you just reverse it
But when you buy in physical store, you can return device simply because you didn't liked it. It must be valid reason behind it - you got it damaged or it doesn't work properly.
There are several stores in germany that offer this kind of service for their customers. They sell thousands of units of one product so they can afford just refunding to certain customers. A few weeks ago, we bought an iron (the thing you straighten your clothes with) and we specifically asked at the store (ALDI, to be specific) if we could return it if we didn't like it and we were told that we had 30 days to return it without any problems
