Wow wish I could get malt that cheap, usually pay £32.99 for mine. I understand that you'd get a decent discount for buying in bulk but that's a great price!
My Choc vanilla stout is really good after about 8 weeks. Definitely much better than when I racked into a corny! The Choc is coming through a lot more now! Give yours plenty of time a condition and I'm sure it'll get loads better!
