Taco Bell has really got a thing for customer appreciation.

First, the company announces its $2 combo meals. Now, it’s giving away free Limeade Sparklers to promote the new drink just in time for summer.

The offer is valid through July 11 or until 500,000 customers redeem  the coupon, so limeade lovers should visit Taco Bell’s Web site as soon as possible. Taco Bell will post a notice on its Web site when all coupons have been redeemed at participating locations. All non-redeemed coupons will be considered void.

Taco Bell describes the drink as “a refreshing mix of cool lemon-lime soda and real lime juice poured over ice and garnished with a real lime wedge.” Limeade Sparklers are available in classic and cherry flavors. Other than that choice, no substitutions are permitted so you’ll just have to break the bank to pay for that 85-cent burrito.
