yes, prices ending in 7 usually outpull other numbers... and i think Dan Kennedy says to include the cents when you're giving them something, but leave them out when your taking money... so your free bonus is worth $5, 697.23 but your product costs $197... but that's just general advice...

the smart way to set your price is to split test it... Try out a price you think is ridiculously low, one that's middle of the road and a third that is sky-high...

you could take it a step further and split test different offers at the various price points...

anyways, basically, let the market decide... and keep tweaking it till you maximize your profits...
