I took this from the first page of the swap thread. It is up to the individual what they feel the value of 6 purebred eggs are worth and what their offer is worth.
As a rule of thumb offers must be equal to the value of 6 pure breed eggs Examples: 4-6 iris bulbs, 6 blackberry starts, and 1 16oz jar of plum jam, 1 hard bound book or 2 couple of paperback books, 2 bars of homemade soap, 2-3 chicken saddles. These are just examples and only to be used as a guideline. Please offer what you feel is a likewise offer and that can be shipped in one of the priority boxes. Remember you are paying the shipping of the item you offer.
