ready to barf

All week I have been spending alot of time uploading pictures to walgreens site. I had 100 pictures in my cart, ready to go. All the quantities and sizes were ready to go, and it was buy 50 pictures for $5, a good deal. As I go to check out, I click on "update total" to see the price. Instead it clears my cart. I hit the back button, but no luck. My week's worth of work, gone : ( I don't even have the patience or energy to go through all those pictures and try to remember which ones I had chosen (we are talking a span of 7 years). Ugh on technology.
