OK, get this. I contacted a vendor for X. They offered Y Z and P Q R S. They've failed to meet expectations when asked for a solution of how to put YZPQRS to make a *network*. All we've got so far is a whishy-washy "we'd put these things together", and no actual reference of how it works.
They've also quoted over 25% on top of list price.
So i contacted my trusted sales vendor that I've known for 5 years, and asked for comparative quotes. No problem, except for one vendor, who won't move the deal registration, as this opportunity was brought to them by the first vendor.
