We recently had price estimates from all of our suppliers for AOPS seven and eight, and we were able to compare those to the prices we paid for AOPS one through six. In those cases, the prices have gone up anywhere between 15% and 40% on AOPs seven and eight from what it's going to be for AOPS one through six.
Another thing we notice is that suppliers give quotes that are valid for only a short period of time, because they are subject to inflation as well, and their sub-suppliers won't give them firm quotes that have price validity. There is significant price pressure across the supply chain.
