no one could do that on a constant basis..for a day...sure, take a loss on the day and write it off as an advertising expense...but even with 2 pre-checked cross sales, $100 isn't going to happen on a daily basis...
we have a $100 promo day coming up actually
again, it's ONE DAY, if we did it for a week or longer, we'd be fucked
Let's say you have a $100 promo day and bring in 200 promo sales on that day...that's a $20K cost. How much does it cost to skin GFY for a week? $25k? Does that mean a sponsor that pays for a GFY skin is shaving, triple quadruple cross selling, etc.? Nope, they used their advertising budget and spent $25K.
Let's say you have a promo on a Friday...well, most affiliates will put you up on Friday and leave you up over the weekend...now they are getting paid the standard payout rate. Maybe they like the conversions and keep you in that spot...was it worth? Would it have been more or less worth it to spend that same money on a skin or massive AVN magazine ad buy?
Promo days are advertising expenses, nothing more, nothing less.
Some affiliates complain about lower sales on promo days...well, possibly because others saw the promo offer and started pushing the same day?
So, a promo DAY at a really high payout...yup, possible to do...over a sustained period...never...without going broke...hell, some programs can't even stay afloat with the normal payouts.
