0 glitch deals. Why they happen:

My conspiracy theory is they do so they can get contact details from new customers and advertise to them in the future. You’re selling them your data for ₹0 because these orders always get cancelled.

Think about it. It’s genius. Make a few 0 glitch deal orders go through, generate hype through bot accounts, get loads of free customer data. Cheapest ad fees they have had to pay ever.
