It's also possible that they realize something was amiss since when previous tenants receive mail, it's not usually in the form of a personal shipment / parcel. Usually, the mail for previous tenants consists of junk mail, previous subscriptions, bills, etc. - so when a priority mail or whatever other shipping service has a package addressed to the previous tenants, it's a bit sketchy looking. It's much better simply to use your real name and address. What you're trying to do is make the package look as normal and boring as possible so it doesn't stand out. Ordering with your real name and address ALSO provides you the benefit of plausible deniability because anyone can order drugs and have them shipped to you. It's a little harder to argue when it's in the form of a random package addressed to the previous tenant! Also, most vendors will not agree to reship or refund UNLESS you have used your correct information - including your real name and real address.
