Amazon is currently having very good sales on sets from various LEGO themes including a couple that are at a pretty decent price points for what you get.
First is the LEGO City City Square (60097) which is at $135.99. That is 28% off the normal price of $189.99 or $54 off. You do get a lot of cool builds with the set including the tram, LEGO Store as well as the LEGO delivery truck which we rarely see.
The next set that I think is a good buy is the LEGO Minecraft The Fortress (21127). It is currently at $67 or 39% off the normal price of $109.99. This brings the price/piece ratio to about $0.07. As with other Minecraft sets, you do get a good amount of parts anyways if you’re just buying it for parts.
Finally, we have a couple of LEGO Star Wars sets to help you build up your fleet. The Resistance X-Wing Fighter (75149) is at $56.72 which is currently 29% off the normal price of $79.99. This is a better price point since it’s mostly a recolor of Poe’s X-Wing Fighter (75102).
The other LEGO Star Wars set that I think is at a good price is the TIE Striker (75154). It’s almost at it’s lowest price ever on Amazon but good enough to recommend. It currently sits at $44.18 which is 37% off the regular price of $69.99.
