If you want flat keycaps, I have a ton of SA R3 1u blank caps. White or orange (OBC). Not sure if I am allowed to link my website here. But I can tell you it would be significantly less compared to what pimpmykeyboard.com charges, even though it is literally the same product.
I also have a ton of DSA 1u caps that are all blue (from old grab bags). PM me if interested I guess. But probably not here because I am not on here often. Try me on reddit, same name.
