I don't mind the short time periods for the announced items that already exist, although I thought last year was better because nothing was offered just once and they balanced times. If something was offered 3am-6am the first time, it would be 3p-6p later, so everyone had a chance to be awake for one offering. (NOT setting my alarm for the middle of the night to buy pixels.)
For the recolors, new items and mystery items I think Gaia is losing business. My free time is too valuable to spend it stalking the cash shop in case they list something I want. So far, I haven't bought a thing, and I was really looking forward to this sale.
***Slighty off topic, but really disappointed in the pet offering. Unless my memory is off, the random pet is twice as expensive as specific pets last year and in recent releases. Wasn't Jet $50 last year? And Lucky $50 earlier this year? $99 for who knows what this year? Really?***
