I thought finding a Lego Friends Christmas Advent Calendar for $10 today was a good pickup.
...but can I interest you in a seemingly complete 10184 Town Plan for $10? No box or instructions, a bit dusty, stickers on the cinema are cracking a bit, but for the price not going to complain. I guess this is why I check CL a couple times a day, haha. Oh, also included 4996 Beach House, and a couple of custom creations. My son was with me and he was ecstatic, so we'll be keeping this one for our Lego town for sure.
The people were moving, and they also gave us a kid's lifejacket that fit my son for free that was only used a couple of times, haha.
