Walmart customers furious after website delays on Thanksgiving

Walmart's website had major delays on Thursday, upsetting customers who were hoping to score deep discounts.

Walmart for the first time this year offered its Black Friday deals online. The deals went live at 12:01 a.m. on Thanksgiving.

But many customers said they weren't able to shop for the items they wanted because of website delays.

Others said their orders were unexpectedly canceled by Walmart after they had already checked out.

Some said the prices shown online weren't the Black Friday deals that Walmart had promised in ads for the holiday. 

Hundreds of customers wrote about their experiences on Walmart's Facebook page. Walmart responded to many of the complaints with an apology, saying the website was overwhelmed by a surge in traffic.

"As our Black Friday deals launched online, we saw an incredible surge in traffic early this morning," the company wrote on Facebook. "The vast majority of customers were able to checkout successfully. The slowness some customers may have experienced was resolved, and we apologize if you experienced difficulty shopping the site."

We reached out to Walmart for comment and will update when we hear back.

The company released a statement Friday about its performance on Thanksgiving, but didn't comment on the website trouble.

"We've said this Black Friday would be the most integrated between Walmart stores and Walmart.com - and we delivered," Steve Bratspies, chief merchandising officer, Walmart US, said in the statement.
