I've worked with fidelity on purchasing a three contracts over the past 5 years, and for the most part, they are just fine to work with. For those contracts, they have called me within an hour of me placing my bid to confirm the price per point, and also to inform me of all fees and who traditionally pays them, then they said "are you OK with this?" So they didn't seem shady at all.
HOWEVER: I attempted to place offers on two contracts in December, 2024, and had a different experience. They were both priced wonderfully, but apparently were not actually available.
When you place a bid on their site, you get an automated response saying that one of their brokers will be in touch soon.
On the first contract, I heard back the same day that it was already sold, but when I re-checked their site again, it was still listed as available. They claimed it was an error that their IT team was trying to fix... a week later it was still listed.
On the second contract, we heard crickets. As in, nearly a month later I got an email stating that "this contract is no longer available."
These two contracts were with brokers that I'd never dealt with before.
All other contracts we worked with Shawn, and she was great.
All this said, I'd definitely use them again.
