I would buy off eBay all the time if I could, but we have contracted vendors and procurement rules we have to follow.
I had to get director level authorized approval to but three 10Gbe NICs off Amazon instead of the contracted vendor to save $1400. It's completely assinine!
Like the transceivers I had to buy for $1400 each when the exact same brand-new finisar was $150. Drives me nuts
