5 orders from Attitude Seed bank in the last 3 years with no problems. I pay extra for the guaranteed stealth shipping.
I get mine from http://bonzaseeds.com/ I like being able to pick a couple seeds for various strains and depending on how $ you spend they include freebies. The freebies change every month too, keeps it interesting. I'm sure most seed resellers are like this but they are the ones I started with and I have NEVER had 1 issue
Most reputable seed banks have freebies according to how much you spend and promotions. On Attitude they have their freebies and special promotions around each major holiday, 4/20 special and birthday promos each year also use the coupon code 420 to save a little bit of money.
I know Attitude doesn't. Some are also getting pretty picky about what forms of payments they take and have been like that for a while. Pick what site you want to order from and find out what payment methods they take before commiting.
