What price drop?
The PRS-505s at Sony Style are still $299.99. The only price drop I heard about was the discounted readers at Borders. I get their newsletter, and they had a coupon for $100 off the reader. Apparently they had a larger than expected response at the Border's online store, and they stopped accepting the coupons early. I think you can still use the coupon at a store that has a reader in stock.
I got a new version of the newsletter today with the coupon amended to say "No Rainchecks." Apparently they just wanted to move a few readers and were willing to take a loss on a few, but they can't get unlimited supplies at a cheap enough price to be able to honor rainchecks.
Of course, none of this has anything to do with whether they'll offer a bigger reader. Just wondering if I missed something about other price drops....
