Woot, Really??? Not puting each 500 quantity iteration in its own space where they SHOULD appear in the blog listing just sux. Now we have to go through the stupidity of callng up "older" after "Older" pages until we finally get to the aggregated listing, just to see what the total sales have been and be able to enter comments (like this one!) AT LEAST put a "Last Page" (obviously for a given date) as a navigation option. [Edit: I see now that substituting a "guessed" page number in the URL field can get you to the Church faster, but you may still have to hunt a bit for the right pew.]
But more troubling, the fact that you are treating this as one gigantic sale, 500 units at a time, but then allowing users to effectively buy (apparently) up to five Blue Oyster Cults in one Woot-Off (and I'll bet there are some that did), simply goes against your policy of one and only one unit per sale. In effect, you are allowing buyers to, after closing the deal on one, go in and increase their order quantity, a situation that has long been prohibited.
Come on, it would be a simple matter to block multiple sales by limiting a given user name to one Breech of Contract per Woot-Off. Sure, some will create multiple accounts, so cross check against IP address, or CC number/PP account or, probably most effective, the computer peanut-butter jelly time address. You DO know how to do that don't you? One savvy programmer could probably set this up in a couple of hours at most; it's only 1's and 0's afterall. If somebody wants to create 5 diferent accounts, with 5 different credit cards, 5 different delivery addresses and use 5 different computers, I guess we can't stop them, but what ever happened to a sense of fair play? I've been a Woot customer since it first went on-line and I've been able to score exactly TWO Bridges Over Chasms in probably 50-60 attempts. What's wrong with this picture? Where is my loyalty award of some simple Basic Organic Concretions? [Edit #2: I see the server auto corrector must be a bit paranoid, replacing alphabet letters #13,1, and 3, which stand for Media Access Control, with "peanut-butter jelly time"?? Sheesh!]
