Not at all, this is a much bigger deal any way you look at it. They got the $35 off that is standard for some packages and new customers, PLUS the $700.
So even if they started both D* and E* one day, cancelled both the next day and paid the $480 total ETF, they'd still have $220 in their pocket above and beyond the normal 'new customer' deal. The likelihood of that scenario is so low that it means even more than that in their pocket.
This has been an interesting thread, and tells me that my next negotiating with E* will be a little more 'forceful' than usual.
