No I can't really think of any place that has seeds that cheap, but even if I found one I wouldn't trust them. It is probably best to spend a good buck on the seeds because that is very relative to the final product. So essentially, higher quality seeds = higher quality bud. Or, you can just get a bag of some regs or mids and get the seeds out of there and grow some sensamilla.
buy the best bud you can and save the seeds from the sack ..and plant those seeds , grow it out , Harvest it , Cure it and then sell it ,, with the money you make buy some good seeds and do it again ..
