Monday marks the holiday you've been waiting for all year: National Margarita Day. Whether you take yours with salt or sugar, frozen or on the rocks, you're going to want to kick back with one of the delicious drinks at the end of your workday.

National Margarita Day may be "one of those completely made up and unnecessary holidays that you can't help but love," as the Huffington Post once called it, but it's also a chance for inexpensive drinks. Several bars and restaurants have promotions planned for Monday, so grab a BFF and take advantage of these discounts, collected from Time and RetailMeNot:

Tony Roma's 150 locations are offering $2.22 classic Romaritas Monday for their own spin on National Margarita Day, called National Romarita Day. Romaritas have Sauza Gold tequila in them.

On The Border restaurants are selling $2 frozen or on-the-rocks house margaritas all day. They're 12 ounces, so drink up.
