does anyone have any insight, tips, or advice on how Amazon does its pricing? I'd expect changes as items go on 'sale' or as replacements become available. but it seems like day-to-day there are very slight variations.
For instance - I've been keeping an eye on the Delta dust collector 50-760...not sure if/when I'll pull the trigger. A few weeks ago I think it was 329. then it was 350-ish. then 338. now today it's 342. it just seems like an odd variation to me...
