Great LEGO Deals Seem to Come in Pairs

I’m noticing a trend in my spending habits, and in the deals that retailers are offering for LEGO products. Again and again, I am finding it to be worthwhile to purchase two of the same set in order to take maximum advantage of sales. The photo below is of some recent purchases, and each came from a different retailer. The discounts were incredibly good, otherwise I would never buy this much LEGO in such a short time frame, and purchase duplicates of sets. For each, I chose sets that I really liked the minifigs or parts so I can expand my collection.
