Oh, well... I have read so many opinions on this! Plus I have experimented quite a bit with auction end days. In my opinion the best days are;
Sunday Evening, Tuesday Evening, and Thursday Evening.
Most people are out and about on Saturdays, I have very, very few sales on Mondays. Start picking up a bit on Tuesday....Sometimes I get a bit of increased sales on Fridays.
The time of the day really makes a difference too I think. I get so excited to list an original when I have finished one, but really, less people are cruzing eBay in the mornings. Most wait until they are home from work, settled in and start searching at night.
Well, theres my two cents!
