Not sure if you have the option to run "mark down" manger specials? Looks like you don't have a "store." Maybe subscribe to at least a starter store to get that feature and just do the month to month subscription which will allow you to cancel store if you decide you don't want it later and not be stuck with it for a year. At least with a small(ebay's cheapest option smallest store you can set a special on the 10 lb boxes and set it where buyers can buy 5 of the 10 lbs and have the discount set where they would get the 50 lbs at the amount you have set $99 for the 50 lbs and then you'd not have to deal with someone coming in and adding 2 or more of the 50 lb orders and paying for them together. I think that might be what happened? I think you are stuck having to ship them together when buyers check out 2 order of 50 lbs at check out. There might be a way to set out of stock option and only have quantity of 1 (50 lb) box at a given time w/o having to relist and when 1 is purchased you can go in and add 1 quantity back each time, but I thinking that would also require a store subscription as well. Maybe somebody here with more knowledge about how the "out of stock ," option works might be able to advise better than myself.
