Pricematch with the special from Pbtech who are selling them for $44.00, then BOGOF at warehouse, effectively making them $22 each!
YMMV!

Use the live chat feature to request pricematch on warehouse app.
Then if you want to bump the total to $50+ you can get another $5 off for your troubles.
I have done this in the past, but it only worked in store. Live chat is kinda smarter
