the 64oz and the one gallon bottle comes out a better deal if you need that much.

Vinegar burns the foliage but does not translocate to the roots to kill the plants. I think vinegar is a good alternative to control weeds but does not offer the same effectiveness on controlling perennial vegetation.

Quote from craving.pho :
Yes, you'll probably have to reapply after a month or so. Vinegar is decent for spot treatments. Depending on your tolerance for artificial chemicals, I use concentrates like this Roundup. They're more effective, longer lasting, and cheaper.
Read the wiki I just wrote about this.

Quote from frozenthorn :
how many gallons can I make with the concentrate? home Depot has the $9.99 non concentrate gallons with wand ready to go. What's the dilution ratio for the concentrate?

About 2.5 gallons.. instructions show 6 oz per 1 gallon.

I wish I had the success with 30% vinegar other folks report, barely withers the ground cover and creeper vines that I struggle to control. Run of the mill weeds it's worked fine on but not the most tenacious stuff that even herbicides struggle with and require regular application.
