Just picked up the Logitech M325 wireless mouse for $5 (before tax) after speaking with a chat agent to Price Match it to BestBuy.
Looks like they're doing an additional discount with PM because BB is selling them for $10. May want to try other products if BB has it lower.
Don't forget to review the product for an additional $2 back in rewards, making this $3 total. If PM only gets you to $10, do the review to bring it to $8. Limit 3 reviews/month.
I added my order confirmation if anyone needs it.
