I have never had a problem scanning in bar codes in Scrapstash - if the product isn't there its easy to add it.
However, with a new recollections punch and 2 Cricut cartridges (I've had them about 5 months), when I scan it in instead of making the usually chirp that its picked up the scan it make a dull thunk noise. I try other things that scan fine and then go back to those 3 items and it is a dull thunk.
I thought I would enter them manually on Scrappypedia and I've forgotten both my sign on and password. That doesn't help at all!
