To the consumer, this functions pretty damn close to TalkTo.
My question is: how many times do you actually call a business to find out about inventory, etc.
I remember doing this in the early 2000's, but in the age of Amazon and transparent inventory on sites like Apple, it's a very rare use case.
From a business perspective, I love the idea of providing better customer service, and if this is a feature that customers actually want, then maybe it will work.
Onboarding businesses will be a huge pain in the ass. But you probably know that already :)
