If an item you're looking for currently isn't on sale, I'd suggest checking back throughout the week as they have daily/weekend specials on their website that end up getting reflected on their eBay store!
For example, currently they have 50% off boots, which can be found here and can be stacked for an extra 20% off.
As always, enjoy!
