Wow, quite crazy deals! I can't believe these popped up.
However, I do have to say, with all due respect, I find it quite disappointing that it seems a large majority of these discounted models have been purchased before most of us had the chance to find them ourselves. I understand these deals are just as enticing to you as they are to other collectors, however it should be said that I myself, and presumably a lot of fellow collectors with smaller collections do not have stable income and loads of money to spend on [more] rare releases or oftentimes, speaking for myself, full-price releases.
I'm going to use Spirit for an example. I've been trying to find a good time to pick up ANY Spirit model and have yet to do so. It 100% feels like a letdown when someone who already has 6 Spirit 320/320Ns in their collection grabs up another 5 of them. Again, this is with full respect, I don't mean to come off as rude, and I understand that these purchases are first come, first serve, however, if I knew that I already had six of an aircraft, and found five more for a crazy deal, I would probably leave most of them for other collectors who could most definitely benefit more from them than I could.
