I noticed that too, bubz. Looks like there are several sellers on eBay who have jacked their prices way up and there was actually one seller that was asking over $1000 for a case.
We paid $20 for a bottle of 200 tablets 2 years ago; the same bottle right now is $39 IF you want to wait 6 weeks to receive it.
They just had another 6.1 aftershock too.
