FWIW, this is a pretty standard price for this via warehouse clubs.
If you’re a US Military Veteran, the regular price at aafes.com is $69.99, and it goes down to $50 during Black Friday sales if I remember right. Last time I bought O-365 was 5 years ago on Black Friday sales (but it’s been the same each year since). Why 5 years ago? Because that’s all the codes Microsoft will allow you to stack on your account. I’ll have to buy again this year.
365 family at Sammys Club is $99.98 for $12 mos.
