My best Ross find ever was a Titan Trypticon for $50, but it does seem to be hit or miss as to which stores get which products. Also, seems like some items they get in quantity, while others only get 1 or 2 per store. (As opposed to Ollie's, where it seems like if they have it, they have at least a case or two per store, or more)
I think there is only one Ross less than an hour from me, and about 4 or 5 that are a not-insignificant driving distance of 1-2 hours. If I happen to be going that way anyway, I will definitely be checking any of them for Soundwave.
