There are 6 food recipes and 6 drink recipes that are needed for L6 provisioning writs. Half of them are super common and are found in almost all guild stores at about 30g. The other half are available at chefs and brewers (respectively) for 1350g.
What I can't figure out is why the vendor available recipes are often listed in guild stores for 2k, 3k, and sometimes more when they can be easily purchased from a vendor for far less. Why are people doing that? Am I missing something?
