From yelp.com - Yeah, I know.... Helen is kitschy, and completely overdone.  But I like to go there in the fall for hiking and occasionally a cabin weekend.  And the only place for groceries in Helen is Betty's.

Betty's is right on the main drag in Helen (GA 75) as you enter town from the west.  They have everything you need for a weekend trip, and some things you didn't know you needed.  The meat selection is great, and I have bought some nice lamb chops and filets there, though the prices are high compared to ATL (hey, if you want city prices, stay in the city...).  They have locally-baked bread and a decent cheese selection for your daily hike, and the deli section is better than your average Kroger with emphasis on German meats.

The beer and wine selection are what amazed me... there were beers in their cooler I'd never heard of (and trust me, I've exhausted the selection at most supermarkets...).  Wine selection is so-so, with one special caveat - they have the most complete selection of Georgia wines I've seen yet.  Believe or not there is some good wine made in Georgia, despite the swill produced by Chateau Elan, and Betty's carries Tiger Mountain, Frogtown Vineyards and a few other legitimate local wine producers.  

There is something sublime about buying Westphalian Ham, Chevre, a baguette and a bottle of Gluhwein for your hike.  Doesn't everyone camp this way....?
