Amazon Prime Day officially got underway Tuesday, with the summer sales event slated to last through July 11. Competitors Target and Walmart are also holding multi-day sales events.

One more thing I found while ping-ponging around Walmart’s sale pages this week: This OB2 scanner from Nexpow. It’s going for $28.79, a great deal off its list price of $79.99, and has far more functionality than any of the $30 bottom-shelf units you’re going to find on the rack at an auto parts store. Could be worth a look!
