Heh, going to call again since they'll now upgrade the free ground shipping to 2nd day air for $1.95 per item. Starting to stetch my luck.
Called the customer service line and I swear I got Gomer Pyle. While he wasn't -absolutely- sure, he could almost assure me (if the stars were in alignment) that they couldn't upgrade the shipping for an order that has been placed. If anyone else has better luck, I'd love to hear about it, just to jab that knife in my side a bit further before you twist it.
