I got my Cricut bundle from HSN and was very happy with the purchase. Shipping was fast and packaging was great. It was offered during a free shipping promo and the bundle made it a very good deal. I'm a pinchpenny, so I definitely did comparing. Other times I've looked at things and wasn't impressed with the price.
I buy a lot from sb.com and although it's usually not free shipping day, I take advantage of the daily deal, plus there is such a good selection of things that I can't get in regular stores.
I also order from J's online. They usually offer free shipping if you buy enough...and I do J's and sb.com often have different products available, so between the two I can get good selections. I wish J's offered free store-pick-up like many stores do, but online has a much larger selection of products than my local store does.
