20th Prime, 50 good price

Being a new collecter im jumping on everything I can, and the fact that I just moved is making it harder for me to know where to look. Well I hit my new local walmart and found the 20th, it was 50 so was that a good price?
Also they had the classics prime and alot others(mirage, gimlock, and 1 more), are they worth picking up (o and the prime and meg 2 pack)?
I also nabed a voyager meg that i will gladly trade
