I hadn't noticed because I haven't bought anything in a couple of weeks. I agree with you that they should have free shipping this time of year considering how much they're selling.
JTV, if you've ever seen that online shopping channel, charges $6.99. They do this even if you buy a $10 item. Even they're doing a lot of free shipping right now. I hardly buy from them because of their very high shipping and return costs. Maybe they do this so people won't return things.
Hopefully QVC will go back to $3. They're a huge company that probably makes millions a day. So why increase their charges?
