In the past, they were for mail in rebates for $5 off various seed kits or light bulbs, and $10 or $20 off various AeroGardens. I'm not sure what the coupons will be for now because the old ones were good for seed kits and light bulbs priced at $19.95 and over. Obviously, with the recent price drop on AG products, this wouldn't apply.
Oh, and don't be surprised if you have to call them to find out where your coupons are. I still haven't received coupons from AGs I registered in September/October.
sounds like I'm pretty safe to order from the current sales then. Thanks!
