Starting a Branch is one of the fastest ways of gaining sb and gb. I have found selling excess food to be one of the best ways to do this. Once you have stabilized your pride selling your excess food is really helpful for the community as it promotes growth for everyone.

PRICING FOR FOOD ITEMS
A good pricing standard for selling food is to add a 0 to how many uses an item has, so let's say a Warthog carcass has 1 use so then you would sell it for 10 sb and so on. Unfortunately, not all uses give the same effect as with small chunks of meat that give your lions less food which I personally take into account and will set to 5 sb even though it has 2 uses.

PRICING FOR OTHER ITEMS
As for selling items the best pricing standard is to directly look at branch sales to see what the latest price for that item is and if you can't find it, asking in the main chat for a price check is allowed.

CREATING A SALE
If you feel confident in how much of an item you can obtain you can create a sale for said Item. Currently for the month of August, due to the surplus in food, I am having a sale because if I did not then the food I have gathered would go to waste if I kept it at regular pricing but for most people that is not the case. Setting your items to a few sb lower when it has been sitting in your branch is standard practice. If a food item has gone past half of its expiring day you should decrease the amount of sb you are asking for.

Hope this was helpful!!
