Costco has this Italian water - carbonated if I recall - 8 bottles in a pack if I recall.
It's always been on the pricey side... I think it was $12 or so when we first started buying it occasionally, likely 7-8 years ago. Then it went up to $16 seemingly overnight - now I think it's close to $20.
It is a luxury, no question. It's not that we can't afford it, just that it is a LOT of money for water, lol. We get it less than once a year now, but it is always a very nice treat when we do.
