I understand your complaint because I've had the same situation happen to me when I was buying sheets of MDF at $12 and then it jumped to $25... it sucks.
I think that since the increase wasn't significant (from what I can tell, I'll compare the old to the new prices here in a few), it didn't warrant a mass notification.
So again we apologize for this price increase, it's hard for everyone and it's not that we are enjoying it either...
BTW, milk around here is $3.78 a gallon and gas $3.89 a gallon... wish my car ran on milk, I'd save some $$$.
Milk here is little over 4 gas is sitting at 4 probably go up here in a day or so again crazy... last time i got MDF 35 a sheet
