If you guys are going to open second (or more) accounts, you just have to watch what you do:
Use a different email address.
Pretty much a given.
Use a different address.
Also a given. If you were to have two accounts open and sending items from both to the same address, it would be very easy to spot.
Use a different IP address.
Make sure you don't confuse your two accounts and sign in with one at both places. If you have [email protected] for home, and [email protected] for apartment, don't sign in with a at your apartment!
I'd say, possibly, use a different credit card. But, I have successfully had multiple (four or five) accounts and used my same two credit cards on all of them without issue.
