Woot offers Garden Safe Slug & Snail Bait: 6-Pack of 2-lb. Bags (HG-4536) for $31.99 (orig. $67.22) with free shipping.

Product Description:
Garden Safe Brand Slug & Snail Bait contains a unique combination of iron phosphate, which is a plant nutrient that occurs in soils, with slug and snail bait additives. After eating the bait, the slugs and snails cease feeding, become less mobile and begin to die within three to six days. This product will control slugs and snails in or on home lawns, gardens, greenhouses, outdoor ornamentals, vegetable gardens, fruits, berries, citrus and crop plants.
