This really is a budget question...I swear. LOL I am wanting to purchase a bottle of wine for around $30-$40 dollars preferrable at Sam's or Costco due to the fact I would get a great buy this way. Can anyone help me please. I am going to Key Largo in a week. I am staying in the Guest house of my friend's sister. I know her favorite wine is a Cabernet Sauvignon. I would like to buy a nice bottle for her as a Thank you gift for allowing me to stay at her home. I am thinking about $30-$40 dollars on a bottle. While I love Cabernet Sauvignon I have never spent that much on a bottle for myself to drink. I really need help with this purchase. I would love to buy a bottle from Sam's or Costco. That way the bottle I get would be an even better bottle of wine. Can anyone help me with this quest?
