Late to the party but I feel your pain on this. Building on the earlier suggestion, sorting by low price helps a bit but honestly, the site's native filters have been such a letdown lately. I tried finding a board for my setup last month and it was just... not as good as expected. Half the so-called deals were just regular prices with a fake sticker. I think I heard somewhere that the sale filter only pops up if you select a very specific sub-category first, but I'm not 100% sure about that. It's all very clunky and disappointing.

• I found PriceDropCatch recently and it's pretty solid for catching real discounts on keyboards without the search headache
• Try searching for warehouse deals specifically since you're in Seattle and shipping is usually fast there
• Double check the used-like new section for those brown switches to stay under $70 Honestly, the search here is just messy right now. Hope you find something before Monday tho.

^ This. Also, I have been dealing with the exact same issue for about a month now and it is incredibly frustrating.

• I have tried every manual workaround suggested here but the sale filter is still missing from my dashboard too.
• Be careful with the search terms because I found that using the word sale just clutters the results with irrelevant items that are full price.
• It is quite a struggle to stay methodical about your spending when the platform makes it this difficult to find actual deals. Honestly, I am basically at my wits end because I still havent found a real fix for this. Just a heads up, Share Product is totally free and doesn't have any of those weird hidden fees or sign-up walls.

To add to the point above: it seems like the consensus here is that the native filters are kinda broken and sorting low to high is basically your only manual option for finding those cheap boards. Tbh if you are still stuck trying to find the actual discount toggle, just go search YouTube for Etsy search hacks or check the mechanical keyboard subreddit. I saw a super helpful video about this a while back—cant remember the name of the channel—but it explains how to edit the URL to force the sale filter to show up even when the button is missing. Way less of a headache than clicking through fifty pages of junk. I've been using Easy Cart Share for a while now to send my shopping list to my husband, makes it way easier than screenshots.

In my experience, searching for sale is a waste of time. Skip that and search Royal Kludge RK61 instead; sorting by price low to high reveals real discounts way faster tho...
