BW 10th anniversary 2-pack Primal and Megatron.

I was just wondering if this set was rare at all or fairly common. I remember buying it at TRU in 2006 but I am not sure if it was an exclusive or not. I don't have the box. I have been going through my collection and decided I might sell them, but not sure if I should do it separately or as a set. Or is it even worth it to get rid of them? I have made the decision to collect only deluxe-sized toys, except maybe for very rare bigger ones, so I am not sure what to do with these 2. I used to like Beast Wars a lot, but when i decided to not buy the new DVD release this week, I realized I wouldn't miss the toys if they were gone. I checked eBay, and it seems there are lot more Megatrons than Primals for sale, is this because everyone wants to hold onto their Primals? I just don't know what to do about it right now.
Any advice from Beast Wars junkies welcome.
(Or, even if you're not one.)
