You can benefit doubly for having percentage donations to charities ...
Some percentage of customers will tack on charity to charged to round number when they are paying w/ non-cash ...
Let's say I am going to buy something that's $36 online ... if the website asks me before I check out if I'm willing to be charged $40 and $6.00 will be donated to X charity - I'm likely to do it, maybe 50-66% of the time or so ...
It only works if the math is immediate for the person, though ... what makes it work is that I instantly realize there's an extra 50% in turning $4 of my money into $6 for the charity and I feel like I'm being asked to split the burden of doing something karmic w/ the merchant ...
Also, you have the ability to do A/B testing and heat-map verification of your UI/UX that competitors won't be able to afford to do ... Do that, for sure, because sheeple.

That's the interesting thing about the net, right? ... You have a site like Gilte Group, where all of the traffic happens right close to noon, when the daily auctions are up on everything ... that allows them to be able to use the cloud and scale the number of machines up drastically for like 2 hrs each day - effectively saying them 22 hrs/day of server costs - so they can operate on that margin ...
Anyways, back on track ... you can drive traffic to your store to sell to it, buy purchasing Google Ads ... when you've A/B tested your Ad Copy to where it's converting predictably (1.5% of people who see it, click it type shit), then you pay Google to send you the traffic ...
It's pretty f**king amazing when you figure this out, because you realize that you don't need to spend 2 weeks running a sale ... you can run a sale in 1 minute =) ... you scale up your servers to handle a bunch of load for a little while, and you tell Google to not space your traffic throughout the month, but just Send It as they get it ... it turns out that for popular stuff, the firehouse is IMMENSE ... they can send eerily more than you would imagine ...
Imagine one minute sales, not one month sales =)
