The cost of inventory on the shelves basically doesn’t matter. The only thing that matters is the market rate.

If those retailers didn’t increase their prices when the price hike was announced, anyone building servers would have instantly purchased all of the inventory anyway at the lower prices, so there wouldn’t actually have been weeks of low retail RAM prices for everyone.

Every once in a while you can catch a retailer whose pricing person missed the memo and forgot to update the retail price when the announcement came out. They go out of stock very rapidly.
