Do you then print them out for your records - for security, should you need them to make a return?
I'd ask if you are self-employed, but that looks obvious as you seem not to worry about having to have MACHINE receipts for tax purposes, and lastly... if you print them out - e-receipts are petty useless as they'd be long lost should you need them weeks/months down the road - if you print them out - is not the paper sheet larger than a machine receipt? and you are still using ink...
Just curious...
Nope. I rarely return items. The last item I returned was a computer I bought from Best Buy. No receipt was needed. They had my purchase history in their computers.
I don't like clutter.
