The items featured are from Oprah's List, which is particular in nature. Oprah's List is as good as a branding throughout much of the developed world, just as is a fashion line. Also, this is supposed to go with an article I wrote, and I'm still trying to figure that out.
I did some price checking.. for some things, like the snorkels, the answer is a resounding yes. For others, like the ice cream machine, one could probably find a cheaper version, but the brand (cuisinart), is well-known with a good reputation. In the article I wrote associated with these products, I do go over what I feel about the pricing in more detail :-)
