I think the 10 pound bag potatoes will be wiser purchase because for 4 pound bag of potatoes it’s cost $2.40 and 10 pound of potatoes bag maybe cost more money but if you multiply 4 pound potatoes bag cost two time then it’s going to come $4.80 that it’s cost of 8 pound of potatoes bag. So I think buying the 10 pound bag of potatoes will be good
