Just fix the bugs and sell a downloadable patch at cost.

I'd pay $4.99 for it.

Yes, that's lame, but I have given in because all the programmers here have convinced me its impossible to expect quality control in software.

p.s. I'll be selling the $9.99 XP Paint Touch Up Kit and $7.99 XP Replacement Hardware Packet for all my products soon! I can't wait to fire all my QC people and then tell consumers that the scratches on the powder coating are "aethestic features" and not defects.
