It's not advertised as being on sale, but this is best-of-season pricing.
Brad's Deals Editor Marisa,
This 2-Pack of 4' Pre-Lit Christmas Trees is $49.98 at HomeDepot.com. Shipping is free. This is one of the best deals we've ever seen on a set like this. For comparison, a single tree like this is at least $40 elsewhere (see here and here). With this deal, each tree is only $25 shipped! Each tree has 70 clear lights, pinecone accents, and a decorative base. Sales tax is charged in most states.
