I was intrigued so I broke down the numbers. I made a long blog post so I'll just link you there, but here is an excerpt...
Photographers, or those wanting to be photographers, post offers like this everyday on every city’s Craigslist. What happens when a professional photography studio makes an offer like this and scales it up to a site with the viral selling power of Groupon.com? Is there a gold mine of sales and referrals waiting for photographers on Groupon or is it a quick path to making your photography a commodity?

$59 for a one-hour location session including prints was not a joke. That was the Groupon deal of the day for Vancouver on July 30th, 2010. Take a moment to look at that page and digest the statistics. Then remember the limitations of running a small photography business — this one in particular consists of two photographers — and the Groupon offers are generally good for one year from the date of purchase. Right now, the deal has sold over 1,200 units and still has 12 hours left to go. Let’s round the total sold down to 1,100 to accommodate those that want refunds or simply don’t book.
$59 x 1,100 sessions = $64,900 in sales in two days
Read on to find out how one local photography studio made over $65,000 in sales in two days![]()

I meant 200 frames clicked through per session, not 200 finals delivered. I know some photographers who would normally to 400+ frames per hour and some that might do 40 so I tried to average it out. That was just part of the rough calculation for shutter replacements, so really just a small part of the formula anyway.
