Sending three different renewals in one package?

My brothers and I are sending our renewals today. I’m thinking to send our packages through UPS instead of USPS (because of delays I’ve heard due to the riots). Should I send all three packages as one (usually UPS/FedEx puts your envelopes in their own packaging) to avoid the cost of overnight fees for three individual packages? (sending it overnight because of the rumors for June 08th) Each yellow envelope has our names to identify which envelope belongs to who anyway.

You can mail them together in one large package but I would recommend getting 3 of those large envelopes for each application. This way things are organized when USCIS opens the package. Try to keep it as easy to follow as possible. I also include a checklist of items in each package so they know what I included and there is less room for error on both ends.
