Looks like most of the Akko (non-lubed) switches are on deal now, too: https://www.amazon.com/gp/product/B08XX7TTZB/ref=ewc_pr_img_1?smid=A2D2ZUZD9IEPI6&psc=1 – $11.99 for a single pack of 45, though you can only buy one
No problem.
I know you said that you prefer to buy stuff from Amazon, but you're going to spend more on those Gateron switches if you go that route and you'll be limited in switch options as KTT Strawberries are only sold by certain vendors in the US.
If you must buy from Amazon US, then maybe look into Akko's line of switches. They are fairly popular in this sub and that's for good reason. Note that some of their switch offerings have factory hand lubed versions. Since you are looking for a linear switch, I'd recommend looking at the matcha greens for starters. I heard many good things about those.
