Replying to Center mounted powder skis?

So I just ordered a pair of Nordica patrons to use as powder skis and managed to get free mounting which is sweet! Unfortunatly, they mismounted them and litterally put the bindings dead center and wanted to know if I should pay to get them remounted... My local shop is like 80$ for remounting!! Any experience with these center mounted or just skiing pow with dead center skis ? Advice appreciated! (Also, btw, I got them from an online store, not my local shop, don't want to call the online store cuz I feel like maybe my mounting instructions weren't specific? Said core center and they mounted true center?)
