I bought a Groupon which was to allow me $100 toward scanning old slides. I thought the price was $. 68 per slide so I mailed 150 slides. Imagine my shock to discover they charged my credit card for 150 "stereo slides & 126 negatives" at $1.58 each. I went by the prices on their first page and didn't realize they called my slides 2.25 (same format as 35mm). I still had red-eye and the focus wasn't that clear. The best adjustment offer they can give me is 30% off $237. I am not happy.
