Your zip code may help determine your booze bill.

A survey released this week by WalletHub found that both beer and wine prices could vary by almost 100% depending on the city. For example, the average price of a six-pack of beer (either 12-ounce cans or 1.5 liter bottles) in Baton Rouge, La. — which boasts the cheapest beer in America — was just $7.41, compared with $13.31 in both Aurora, Ill., and Chicago — which are tied for the honor of priciest beer in the nation, beating the runner-up by more than $3.

Wine prices show a similar variation. The average price of a bottle of white table wine was just $4.24 in Indianapolis, but a whopping $13.22 in Portland, Ore. (and no doubt, many a Portland hipster spends more).

So what’s with the vast price variations when it comes to booze? “There’s no single explanation,” says IBISWorld alcohol industry analyst Nick Petrillo. “Rather, the price of alcohol varies because of unique regional characteristics, laws and, to a greater extent, people’s ability to dictate with their wallets what they will and will not pay for a drink.”

But no matter where you live, there are plenty of ways to save on booze. Here are a few:

Shop later in the year

“Some of the best prices on wine are in October, when most wineries are releasing their new vintages; they want to clear out the old to bring these in,” says Teri Gault, CEO of The Grocery Game. And surprisingly, the holidays might yield some deals: Gault says that during the holidays, many drugstores deeply discount alcohol, so it might pay to shop there then; just be sure to price check.

The cheapest (and most expensive) places for beer

Know where to shop

Costco and Sam’s Club often have great deals on alcohol. Kendal Perez, a savings expert with Coupon Sherpa, says she finds her favorite wines for $2 to $5 less at Sam’s than at local liquor stores. “Wines at warehouse club stores are usually about 30% less than a wine store,” says Gault.

Gault says that you can get some significant deals at supermarkets and drugstores when you use instant rebates, which many offer. “Sometimes, supermarkets, like Ralphs, a Kroger banner, offer a mix and match of 6 wines purchased and gives $15 in instant credit for groceries at the register,” she says. They also offer coupons often. Gault says that BevMo is also a good bet.

Buy in bulk — and if that isn’t feasible, haggle

Many stores discount alcohol if you buy by the case, says Gault. It can also pay to ask for a reduced or discounted price (point out that you’re a loyal customer); you won’t always get it but it’s worth a shot.
