[Lititz]

Some of these prices changed last night. Some are now a very small amount lower, others now are substantially higher. Example: 16-50 now shows list price at one of the stores. Perhaps these were automatic/scheduled reversions to list prices that will be adjusted back down later this week; that seems to have happened sometimes before.

[Architecture]

Yeah, what gives? I've been looking at the DA 15 and just this morning it's up $50 more.

[sculptor666]

150-450 is $150 more at b&h. also "regular" prices vary wildly between the two stores? and reward$ are hit or miss?

[Lititz]

16-50 is back to $668 already. Maybe other prices changed too, but I didn't check. It looks like sale prices automatically expire, and then get reviewed and possibly re-established (either due to automatic comparison with competitors, remaining stock, or other relevant variables, or by having someone review them personally).

Price differential between the K-3 and K-3ii is now $32, with price increased on the K-3
