Would you accept 200 CSC for your Collection of Puzzle Riddles?

Aaaaaand I'm dumb. I thought you meant you were iffy on even doing 300m, but re-reading, you meant my 275m offer, huh? >< I'm happy to do 300m.

As an alternative offer, I could also offer the original 275m pure plus all of the boosters in my "Boosters for trade" shop. It's about 35m worth (at ss value).

I could definitely do 300m, but I'm happy to let you sit on the offer for a bit. I'm in no real rush as I'm still a few tiers away from being able to use the serum, and I don't want this exchange to cause hard feelings/tension.

I'd love it if you could do 250m, but that's probably asking too much. :P

Does 275m sound at all reasonable?
