CHICOPEE, Mass. (WWLP) – Christmas is less than two weeks away so hopefully you’re finishing up your holiday shopping soon because it is predicted to be a busy weekend for shoppers.

It’s likely people will be flocking to the stores to try to finish up that holiday shopping.

Earlier this year the National Retail Federation predicted sales during November and December would grow somewhere around 10 percent compared to last year.

Additionally, households are also expected to shift back to in store shopping and a more traditional holiday shopping experience. With that being said online sales are still expected to grow to 11 to 15 percent.

Despite the ease of online shopping, experts have been recommended people shop in person this year to avoid shipping delays. Here’s a few dates to keep in mind.
