Sorry, can't help you out on this one!
WOW ... talk about pricey!
I know they have gone up, but that seems over the top.
I did buy some before Christmas at Michael's ... forget the price.
But with one of their 50% off coupons, I know it sure made a difference.
Looks like I better make a habit of nabbing them with Michael's coupons
and keep my blade stash replenished!
