I always ship within 24 hours of receiving payment and send out a ship confirmation
holy cow if i see this sentence again on these boards!! i think we all (or most of us) ship within 24 hours, but that makes NO DIFFERENCE...they're not rating us on when we've shipped the item-they'll never know that anyways, they're rating us on THEIR perception of how long they think they should wait to get a package...if their expectations have been exceeded, they will leave a good score...if they have high expectations and they're not met (even if they're unreasonable expectations), they'll still leave a bad score...
...this area will never change in the fact that we will have very little control over this rating...of course, there are ways to 'deal' or educate the buyer about this section....sorry, if no one else jumps in to give you good ideas, i'll try again tomorrow, since today my brain is dead-very little sleep lately...but you sound like a very articulate person-i'm sure it won't take you more than 10 minutes to come up with something for the buyers that won't sound condescending...i'll have to create one of my own soon if i ever get back to selling...
