Like Todayillbebetter we used to buy the cream cheese frosted blueberry compote cake things from Safeway.
I also miss Blockbusters. When dh and I were first dating, and for many years afterwards, we'd go at least weekly, get at least two videos (later dvds, then blu-rays) and see what sweets etc were on special offer. We also bought our first Blu-ray player there, still have it. I was sad when they closed, but I suppose that one person hiring one or two films a week, even for many years, isn't enough to keep a business afloat!
I much prefer physical discs off our shelves to choose from than a digital download, but I also prefer a proper tv listing than something like Netflix. I find it easier to choose from Sky listings than Netflix at home, I think that is just how my brain is wired. Dh can't understand it, he's the opposite.
In one town we used to live in, after Blockbusters closed, a friend's dad opened a 'corner shop' at the end of our street. One side was sweets, bread, some other groceries etc and the other was dvds. We used to go there sometimes but there was nowhere near as much choice as Blockbusters had had and we weren't quite sure if he had the right licences or whatever he needed. He also started selling illegal tobacco products from overseas (his daughter told me) so we stopped going. He closed soon after, but he and his wife have a big holiday every year and I think he was using it to fund that one year.
I also miss Woolworth's sales. Up in The Metro Centre, near where we used to live, the was a big Woolworth's and we used to go there every time we went to The Metro Centre. Unfortunately they couldn't survive on one person buying everything from them at sale prices.
