Looking at Walmart prices on grapes, I'm getting between $2.49 and $3.99 per pound. So unless they're basically free down by you, I can't see getting 2.4 lbs for $2. Plus, I always get skeeved out when I see those unrefrigerated baskets of fresh fruit at Walmart. At the grocery store, they're in a chilled section, with that mist spraying on them.
When I buy grapes, I get between 1 and 2 lbs. I can't see getting 2.4 lbs for 1 person.
Went to Walmart before my shot this morning. Here are the grapes I saw:
And that price is for the whole bag.
