YES! YES! YES! @brightestspark Your solution solved my problem. Thank you very much. When using the CSV Import Suite, make sure the following are set for both the parent and the variation imports.
stock
stock_status
post_status
manage_stock
We were managing stock at the individual variation level, so it seemed counter intuitive to set a stock quantity for the parent item. Once I merged the parent items with these fields filled, the prices reappeared.
