I just used a Starbucks gift card I had been given. I got it back from the Barista with $.90 remaining. Likewise I have a gift card from Best Buy with $4 remaining on it.
I’d like to see a more charitable way of dealing with ‘left-over’ gift cards. If you have less than $10 left stores should ban together and offer to split the difference; give me the option on the spot to have 50% or more be donated to a worthwhile charity like the One Campaign.
