Hi Gazza,
Please can you add a category for Seeds under Home & Garden, You already have
Garden, Yard & Plants : Plants & Trees: Seeds
I think a good layout for seeds would be
Garden, Yard & Seeds : Vegetables
Garden, Yard & Seeds : Flowers
Garden, Yard & Seeds : Ornamental Grasses
There are more seed varities that can be added
I think giving seeds their own category in the layout above will make it easier for buyers to find
Thanks
Phil
