I know of multiple dealers in Tulsa that sell lowers. $44 is a deal though OTD imo. I have bought them locally for $50-$55 for PSA and Anderson. Spikes for $90ish. I have never been able to find a FFL that would do a decent fee for multiple lowers. So when you see the $30 online sales then add $10 in shipping then another $10 per at minimum for ffl. It kills the deal.
I like to have Snake roll marks on mine so I've not purchased any under $50..
