Last weekend, I was trying to use a promotion code on Kodak Gallery's website to get free shipping. I tried and tried. I probably tried 4 or 5 times. But, it simply wouldn't work. I checked all the details about it and still couldn't figure out why it wasn't working. Finally, I gave it one last try. I had been typing in the letters in all caps myself. Instead, I searched for a spot on the webpage that would let me copy the text (by right clicking with my my mouse). I copied the text into the promo code box this way. And... Finally, it worked!
I wanted to share this in case anyone else has run into the same cunundrum with a code that simply won't work!
