12oz hex sell about twice as fast as 8oz when they are put side by side. 1 lb round are a bit yesteryear and to be honest customers seem to value the hex 12oz at the same prices as the 1lb round. It does depend to some extent on your potential customers, what they have been used to and what they compare your product with. I supply a shop that had been selling 1lb round from a beekeeper who had to stop keeping bees - they went straight in with 12oz hex at the same price they had been selling the 1lb round - not a single comment from existing customers.
Presentation is everything - you need a good looking label .. I get mine printed in sensible quantities by Stikaroo - they took my design and fiddled with it and I just update the BB date when they re-print. There are rules for honey labelling that you need to adhere to.
There are a number of jar suppliers - I buy from Freeman and Harding who give a discount for BBKA members, promotional prices at the shows and they ship beekeeper packs with the lids on. Be careful, there are some cheap chinese jars about and they don't look as good.
Lids - lots of variants - I like plain gold but it's your taste that will govern that decision. Security labels are a good addition if you end up selling via retail.
You are probably best, at this stage, to look around your area at who is selling 'real' honey, what prices they are selling for, what sizes, what type of jars and what their labels look like. Local honey is well received by those people who understand the difference between what you sell and what is found on supermarket shelves at low prices (A Blend of EU and Non-EU honey tells a story on the label) Sussex Weald Honey will tell a better story ...
