Gardener Guy,
About two years ago, I was in your shoes! I found the best way to get my name on mailing lists was to google something like "
seed catelogs" and then see what came up. I visited sites and if I liked the site, then I put my name on their mailing list. More time and effort, but it worked well for me. Last year I ended up with ALOT of catelogs!!!

Ever wonder what to do with the catelogs after your done with them??? I use mine at school...I cut the pictures out and let the kids glue them onto construction paper. I'm sure local daycare centers or elementary schools would like all of your catelogs when your done with them.
