Actually I think you can have 3 outside links on your about me page as long as it doesn't go to another auction site.
Ronnie: she might want to just do auctions without opening the store to get her product started (i think you have to have a 10 feedback anyway to open a store) for like 6 months or so, then she'll have a following and if it is branded the same name as her website, it will be much easier to find.
I'll give you a fee example:
I sold in 31 days.. 998.15 just short of the power seller mark
and my total monthly fees were 104.14 so it's about 11%.
Much cheaper for me than when i had my store at the swapmeet and MUCH much easier to manage.
