>>11291099FB marketplace is the best way to build a lego collection. During covid I swept up all sorts of poorly-listed lots for 15, 20, 30 dollars each and amassed a comprehensive collection for the cost of 1 (one) big flagship set. I even made money doing it. Nowadays I run my collection net neutral so I essentially pay myself for time and might be 100-200 dollars up at any given time to buy a new set with no remorse. PAB is not only a ripoff for any sort of bulk but it's also hyper-specific and slow as fucking balls. In the last few months the system has essentially frozen solid, so you can't trust that you'll actually receive any pieces that become discontinued during the numerous months they're chewing on your order.
