Sounds like Enco is trying to see if they can get away with increased prices and less discounted sales but they'll probably realize that there client base will only really jump on there good discount and prices.
When 30-20% off, Free ship comes back, then my cart full of stuff will be purchased.
Some GJ members do get better (stackable) sale codes than the typically sale codes that most of us get and have posted them here in the past.
You also need to shop the HotDeal monthly catalog for the best (stackable) deals but check your cart and the prices as the deal may go away if it's no longer in the HotDeals.
EDIT: This sale has been extended and Wilton vises are on deep discount.
The Wilton 4" bullet vise is only $260
