mulegolf Have done a lot of trading in with RBG. Always take the 'store credit' as it will give you +50% more. Then of course, you'll buy more toys.
Never a problem doing this. It takes a few days after they get the clubs before any credits are posted. Plus the clubs are always in as stated condition(sometimes brand new in plastic!); maybe better than Callaway pro-owned lately.
Just make sure YOUR clubs are as stated. They do check condition and possibly would come back with a lower offer if damaged or in poor condition.
