I do not know any solid answers from research for this questions. Half the things you read say that '.99' makes some people interpret the price as being lower than it really is while the other half of research says that people interpret as being an underhanded tactic.

Personally, I prefer flat dollar prices. I'm much happier with $25.00/mo as opposed to $24.95 or $24.99/mo. I read them all as "$25" anyway and I prefer nice round numbers.

ymmv.
