Allow pricing in prices less than a penny...

A lot of the stuff we sell, has a price that is $X.xxxxx.  In other words, it may be $36 for a thousand, which works out to 3.6 cents per item.  I can enter 0.036 in the price tables, but it either rounds off or truncates the last decimal, so the customer is charged either $30 or $40, instead of the intended $36.

This is a really simple thing to fix and could be done in hours.

Alternatively, some place to enter an extra fee could correct this (like in the example above, a $6 setup fee would correct it in some situations), but that may require having many many price tables, one unique to each item, and it may not always give the desired results if we have multiple quantities of items and all those quantities don't result in a price of $X6.00
