Groupon offers $50 in HomeTown Buffet Gift Vouchers for $30. (You'll be emailed five $10 e-vouchers with unique codes that must be printed and brought to the restaurant.) That's tied with last week's mention and the best price we could find for $15. It's valid at participating HomeTown Buffet, Old Country Buffet, Country Buffet, Ryan's, and Fire Mountain restaurants. The vouchers expire 90 days after purchase.
