sea of green - Aurora seeds

I'm getting ready to do a sea of green. I'm look to order 50 feminzed Aurora seeds with a CC. What's the cheapest/most reliable website to order them from? Everyones input is appreciated. Thank you

Any input would be great!

Also has anyone tried guerilla-growing.com ? They have cheaper prices then the single seed centre but I more or less want a secure and reliable website for the best price.???

Just a suggestion, if ordering that many, i would try contacting the breeder (via email) to see if you cant get a bulk discount.
