This is my first post so hopefully I get this right. On Amazon, by typing in Tervis and sorting price from low to high, you can find a ton of super cheap Tervis cups as add ons. A lot of small or random universities plus sororities and fraternities, some letter cups etc. Prices start around $3.63 or something like that and go up. Many with lids are $5-7 and the lids by themselves alone cost $4 for any size so its really a great deal. I know for Prime Members you can get add on items with $25, I think non prime is $35? But I was able to load up on several of these to save for Christmas since I have a lot of friends and family members that love Tervis cups.
