Hi 77Pat,
Hopefully you warned him that the better manufacturers and retailers don’t generally “negotiate” (see post #6 here) or have “fake sales” with large discounts based on the time of year or holidays (see the guidelines here and post #5 here). While they may have sales with smaller discounts … I would treat retailers or manufacturers that negotiate their prices or have “major holiday sales” as a red flag because manufacturers or retailers that sell good quality/value mattresses don’t need to negotiate or have “fake sales” with misleading discounts to create a false sense of urgency and they sell good quality/value mattresses every day of the year at prices that are already very reasonable.
You can see some comments about the changes they made to the Brooklyn Bedding site in this post.
