How much lower is it and if activating a ga does it go lower n how much if so?

Seems to be 15 minutes now (instead of 45). I have GA, so I don't know if that affects it at all (I suspect it's the same for everyone, though).

If you buy something, it'll say exactly how long you'll have to wait to buy again. And it's shop-specific, so you can buy fron every shop at once, then wait, then buy again from all of them.

it's 20 minutes for regular accounts, now.
