If you are looking for fashion sewing, I recommend e-patterncentral.com or sewingpatterns.com. These websites offer original and noted pattern companies. On the sewingpatterns.com, there are sales for different patterns at certain times. Sign up to have these sales sent to you and get a Butterick sale for $2.99 per pattern, where non-sale price would be $6.99, plus. Vogue, McCall's and others offer sales that you cannot refuse.
If you are sewing for the children and baby, SewBaby.com has a great selection.
Good luck on your adventure!
