Groceries don't have to be expensive if you're willing to go a little out of your way for them. If you live in a city or town that has a produce market or farmer's market, you'll save a ton of money. Go to a butcher rather than a supermarket for your meat, and you'll have more to spend on Surge.
For example, today I went to my butcher at the Haymarket here in Boston. They're known for their sign that says "Order your freshly killed GOAT. Half or whole!" But they have great beef too. Today I got 3.5 lbs of steak for $9. It would have been $10.50 but I go there often so he cuts me a deal sometimes. Still, 3.5 lbs of quality beef for that price seems like a no-brainer.
The Haymarket has tons of fresh produce for very cheap. I've seen such deals as twelve lbs of tomatoes for $2, three lbs of strawberries for $1, five lbs of bananas for $1, etc. You can get a pound of spring salad mix for a buck, a pound of blueberries or raspberries for a buck, or 6 ears of corn for a buck. They were selling large boxes of mangos for $3, bags of pistachios and other nuts for $1, and bags of exotic spices for $1. Next week I'm going to try some of the Indian spices they sell.
All in all, today I got 6 lbs of potatoes for a buck, 4 lbs of bananas for a buck, and a pound of spring salad mix for a buck. Not to mention those delicious-looking steaks. Fourteen and a half pounds of food for $12. Not bad at all.
My point is, if you have the option, forget about your grocery store and go to the farmer's market. Sure it's loud and it can smell bad from all the people, but it's a damn sight better than Shaw's or Winn-Dixie.
