have them sent anywhere BUT where your garden is located. use an established, well known company because they have the best stealth and usually offer replacements should the worst happen. ones i have used are and would suggest (in no particular order):
seeds direct (also seedbay, a side project of same company)
heavens stairway (and cbay, also a side project)
klozit king
dr. greenthumb.

these people have been in the biz for many years and all have excellent rep's
