Many Walmart customers reacted negatively about the store’s frozen pizza recipe last year — accusing the retail giant of trying to fix something that’s not broken.

Now, Walmart is responding to the criticism by switching back to the old pizza crust recipe, and on Wednesday, stores all across the country are giving away free slices to celebrate the relaunch.

Last June 6, more than 2,500 Walmart stores throughout the United States started giving away free slices of freshly made Marketside Pizza near the store’s pizza section. Pizza choices will vary by store, but the options include cheese, pepperoni, supreme, and “Ultimate” meat. Best of all, you don’t need to buy anything to grab a free slice, though the giveaway is limited to one slice per person.

Not every Walmart store is offering free pizza and some stores are staging the giveaway on different days this week, according to the company. However, Walmart recommends that you call your local store to make sure it’s participating before you show up asking for a slice.

“Some people (not naming any names) got a little crusty when Walmart tried to improve on pizza perfection,” Walmart said in a statement, “so now the retailer is flipping back to the original crust that customers craved — and giving them a piece of pizza to celebrate!”

So, thank you to everyone who complained.
