Sam's Club currently has the 7.5' Pre-Lit Twinkly Multicolored RGBW LED Douglas Fir Christmas Tree on sale for $299.91. This particular tree has 480 lights and 2541 tips which is 45 more lights then then Michael's tree and 419 more tips then then Big Lots tree (which is now OOS anyways).
I know the big question will be does this have the 2nd generation Twinkly controller/lights or is it the first gen. I have no idea, but it's from Sam's Club so if it's not what you want you can return it fairly easily. I've ordered 1 and will update on the generation once I know.
