I'm not a prime member-son is-but as near as I can tell onlyPRIME advantage is faster shipping-
shipping is still free if it is over $25 I think
Mine was $75 because of the high 9.25% sales tax in Jefferson La
Still a good deal-I am really really curious what velocity my Diana 350 .177 is getting with the very light pellets I use- 4.2 and 5.2 grains-
guessing maybe 1200 fps-and if it was still igniting oil-much higher.
