Why are 25i and 25c nbome so much cheaper than 25d or B or N or iP?

Thanks

synth might be easier if they're using leftover 2c-i or c (I dunno if they still do that, or ever did)
Vendors probably wanted a lot of 25i/b/c, because that's what customers wanted, so they stocked up. Supply and command

I see plenty of cheap 25b
