I'm late to the discussion, but thought I would add my $0.02.
I arrived around 1pm on Friday, and was among the first 15 people or so lined up. The goal of my trip was to pick up a few of the copper pieces with the cast iron handles and 2.5mm thickness (from the M'heritage 250c collection). I would estimate that there were only a couple dozen of such items at Friday's start - I don't know how available they were during the special access event for Meals on Wheels on Thursday evening. The 250c items probably were all gone within the first hour or so on Friday. I will note that there were many more of the thick copper pieces with brass handles available throughout Friday, however they were priced higher.
If anyone is interested in buying a 2.5mm copper saucepan with cast iron handle + lid, please let me know. After getting home, I realized that my 2qt and 2.5qt are a little redundant
