I know this article is a year or two old, but it might be worth noting/updating pricing info updated for items linked in the article. It turns out the Scepter cans from Bottom Line are priced at around $28 each, but they also charge exactly that much for shipping (it seems they charge a 100% shipping charge on all items), making them almost $60 each! That changes the cost basis considerably. I’ll give the Skilcraft/LCI branded ones a try since they are around $33/ea shipped directly via Amazon, assuming the sellers are legitimate (which is another issue with these items… knowing the pedigree of the seller). Caveat emptor.
