Are you intending to migrate the full history across? I know I came across this several months ago while you were still testing. I found it very handy for checking model names of things I'd bought 5+ years ago, particularly when troubleshooting stuff on hand-me-downs I don't have direct access to anymore. Losing that is quite painful.
I'm hardly expecting it to change at this point, but as feedback regarding deal of the day: I'd fairly often come to the site once a day just to see that. If I go to the deals page now, it currently says there are 1304 deals. Pretty much each sub-category has no less than 20. From my point of view, I see that and I don't have any inclination to sort through all of that trying to find something that's worthwhile on a whim. I'd tend to at least visit the site most days to see the daily deal, which would often directly or indirectly lead me to buying it or something else. I can't see me visiting the site anymore unless I have an actual need for something with this change. Like I said, not expecting anything to come of that, but felt the need to leave my own tuppence worth.
