These cups will not fit the lids that are on the shelf at Sams, do not buy the lids that say fit the 16-20-24 oz cups. You'll return them!!!!

These cups are junk! You can count on throwing half of them away as they have holes in the bottom, I found some that the entire bottom fell out and drink spilled everywhere. I would not buy these again.

Great cups, do the job they were made to do. I have noticed the last two times that I have purchased there have been several cups missing (5 or more) out of the box.
