World Vegetarian Day falls on October 1, and this year Whole Foods Market is getting in on the fun. To celebrate, the high-end organic supermarket, which was recently acquired by Amazon, is going to retail organic bunches of kale for $1. And this offer won't be limited to World Vegetarian Day — it'll be valid from September 27 to October 3, while supplies last.

Get your kale while it's hot (and cheap), people!

"Each bunch of kale meets the USDA's standards for organic produce, and offers a good source of dietary fiber, protein, thiamin, riboflavin, folate, iron, magnesium and phosphorus. It's also an excellent source of Vitamin A, Vitamin C, Vitamin K, Vitamin B6, calcium, potassium, copper, and manganese," reads a press release for the promotion.

While Whole Foods is typically known for its hefty price point — the store is often called "Whole Paycheck" in reference to its expensive rates — it's lately made headlines for the exact opposite.

After being acquired by Amazon, the company slashed prices on items like bananas, avocados, brown eggs, rotisserie chicken. The price drop certainly got the attention of customers. Business Insider reported that Whole Foods experienced a 25 percent increase in customers. And, in some cities, the effect was even more dramatic: Chicago saw a 35 percent spike in customers.
