If your dealers are fair to you, an ounce, and no less than half oucnes are ideal for buying. A fair dealer should lower the cost of the overall weight when buying in bigger quantities, but in some cases, some dealers won't do that.

You see, some charge lets say $40 an 1/8, average cost I think, and there are 8 1/8's in an ounce, so some prick dealers will just keep it at that cost, and charge you $320, which is a huge ripoff.

Around here, 1/8's are $35, and I usually buy an ounce once a month or so. For me to buy it in 8 1/8's, it would run me $280, with 8 trips. If I were to buy in 1/4's, for $60 each, it would still cost me $240, in 2 half ounces for $110 each, $220.

For an ounce at once though, I pay $190, so there should be at least some savings when you buy in ounces.

If there isn't, I suggest stick with small bags and find a new source for larger bags. If your dealer only deals with small amounts, there is a good chance they either won't sell an ounce to you, or they will rip you off, for one main reason, and that's money. You get a dealer who sells grams or 1/8's, and he sells an ounce for less, that is about a $100 they lose. There is more money selling in small amounts, but also more risk.

Either way, find a good dealer and go for it.

Eyeballing an ounce varies greatly. It all depends on how dense the buds are and that is very different from strain to strain, and there are thousands of different kinds.

Best way to know is to buy a scale. That's the only way to 100% know. Any other time without a scale, you're maybe half right.
