I’m a big user of Amazon, but have never bought a thing on Prime day. I just don’t see deals on anything I’ve been thinking of buying. Maybe I”m not doing it right...
Of course you're not doing it right! Don't you know that you're saving money, if you're not buying something that you can actually use? Buy! Buy! Buy!
So what if you don't need a left-handed widget! Buy five of them and get even bigger savings!

you’re doing it exactly right: don’t buy stuff you don’t need just because it’s on sale ... the principle is the same whether stuff is on sale online or in brick and mortar stores ...
