Quick Ship Electronics via eBay offers the open-box 6th-generation Apple iPad 9.7" 128GB WiFi Tablet in Space Gray for $329.99 with free shipping. That's tied with our mention of a factory-sealed unit from Black Friday week, and the lowest price we've seen. (It's $49 less than the best deal we could find for a factory-sealed unit now.)
Note: A 1-year warranty applies, but it's unclear who backs it. It may not ship in original packaging.
Some of the changes we've made amid the COVID-19 outbreak are likely permanent.
