Wow, that's a bummer about the warranty. Never knew it didn't include tablets.I ordered a 10.5" WiFi 256GB in Silver on M (6/12) and received it Th (6/14). It was $30 off. Currently, I only see 64GB 10.5 WiFi models (also $30 off) online. They don't have any 2nd gen 12.9 ones on their website; just a 1st gen.
Touchscreen tablets are excluded from Costco's 2 yr warranty.
