...or the half-price fun, at any rate.
I just talked with Marv from Freestyle today. Apparently Arista Premium 100 has been discontinued, and they are limited to available stock, which is mostly 24-exp. rolls (and bulk rolls, I assume, though I forgot to ask).
He said the 400 has not yet been discontinued.
On a positive note, Legacy Pro 100 (Across 100 emulsion) is on sale for about the same price that Premium 100 was going for: $1.99 per roll of 36 exp., and $1.89 per roll of 24 exp. (At this pricing, I fail to see why anybody would buy the 24-exp. rolls.)
