I suspect we all know that one can price compare QVC to other stores in every category. Yet that's not what was stated in the OP's post #1 or #7.
I'm not a fan of hyperbole.
Every year I enjoy looking at what's new. I grow tired and bored with looking at my same old decorations year after year. Each October I go through items I have for both indoor and outside and decide what to keep and what to donate.
My days of holding on to the Polonaise, Kurt Adler, and old Germany ornaments are gone. I avoid glass. Now a days I drop things too easily. I buy new shatterproof. I like to see what's new, and the improvement in products each year. I eliminated plug-in electric items and have gone to battery operated only, both inside and outside of the house. Many are powered by rechargeable batteries.
Seeing what QVC has to offer during CIJ before any other retailer, affords me the opportunity to plan ahead to decorate. You can order, and basically put something on hold, and not have to pay for months in advance. That means you are free to see that other store have to offer once their merchandise comes in. See something you like more? Then cancel your QVC order. Win-win for me.
