3-5 days.
Actually it would depend more on the pack date and the fridge temp as well as if it is cryo vac sealed or just plastic wrapped. For cryo at least 15 days safe without worry and up to 1 month if packing date aka kill date is only a few days prior to purchase and if just wrapped 5 to 7 days of store packing date. However if it's just wrapped I would unwrap it for aging.
