I mainly sell Milk Snails, though I am branching out into a few other species. Soon my collection will be:

Milk Snails

Grove Snails

Helix Pomatia
Cornu Aspersum
Asian Tramp Snail

I already have several of these species ordered and will be arriving soon to my stock. Hopefully they will breed too, so I'll have some for sale.

This is unknown. Snails breed when they want, I cannot force them. Eggs can take up to 4 weeks to hatch, though most hatch in 15 days. Babies need to go through a culling process so that also takes a few weeks to a couple months. You can be added to the waitlist, but I really don't know when some will be available as I have no control over nature. Snails do what they want, when they want. :')
