Varies widely in my experience. I believe it really depends on when you submit (i.e., is a big special running?) and what you submit. Oddball cards will always increase your wait time. Mine have been done in as little as 5 day and as long as 45 days.
My last one that I sent about 3 weeks ago came back in exactly 7 business days(for a 6 item submission). Make sure to label the outside of the package clearly(something like 7 day submission voucher) because it is suppose to only take 7 business days max for those collector club free submissions
