New Toker - Questions.

Hi, I'm new here and have some questions about the herb!

A few weeks ago I tried it for the first time at a party and loved it. Million times better than drinking when you're with your mates! I've since met a dealer and am looking at buying some marijuana to have by myself. He charges £10 for 1/10 (about 2.8 grams) is this a good deal? I would also like to know how much I'd need to make a joint, that would get me high, using pure pot, no tobacco. Thanks everyone in advance!
