We would like to use eBay's Markdown Manager, but it doesn't appear to be directly integrated into GarageSale 7.0.8. Can we use Markdown Manager at all? How will this affect our GarageSale listings? For instance, if we use Markdown Manager through eBay, would this constitute a 'revision' to our listings, and negatively affect the GarageSale sales data reports? Would it create problems when we re-list unsold items?
