So, I tried the shower curtain thing, and it worked! I threw it in the washer with a week's worth of dishcloths and a glug of bleach, and it came out ungunged and untorn. And as an added benefit, the bleach had some mountain clean/spring fresh/who comes up with these names? scent, and it's lingered on the shower curtain. So the shower is both unslimed and nice smelling. Yay! I priced liners at Walmart today, and they ran from $2 to $10. If I'd had to replace it I probably would have bought the $7.97 one, so this experiment has saved me $7.97! The old liner is in excellent condition, so I fully expect it to be around for at least another year or more with continued washing.
Walmart was a good deal for me all around today. I had my price book with me, and I found several things at a significant discount. Overall, I saved 27% over Kroger or Target pricing. And only two items were on sale, everything else was regular price. Unfortunately, that doesn't mean that Walmart is cheaper all around. I didn't do a full price shop, but for the items I checked there were just as many higher priced as lower priced. But I'm pretty well stocked right now, so other than milk (I got home and realized my milk was seriously out of date- poor planning on my part) I don't really need anything else.
To top off my day of savings, I took a bag of books over to Half Price Books and made $5. More money in my pocket and less stuff around the house collecting dust. Sounds like a win/win to me!
