It's ONE entry PER PERSON / CELL / ADDRESS
So yes, a husband & wife can each make their own entry. That's what I'm doing for us.
If you enter using your cell to text, then you cannot use your e-mail address to enter again that SAME day.
You cannot enter using your kids' names' if they are minors.
Quoted from the rules:
Entries are limited to one (1) Entry per person/Cell/Address for each Daily Sweepstakes, regardless of method of Entry or whether one person has more than one Cell/Address or more than one person use the same Cell/Address, resulting in a maximum of 60 Entries allowed for all Daily Sweepstakes. In event of a dispute regarding the identity of the person submitting an Entry, the Entry will be deemed to be submitted by the person in whose name the Cell/Address is registered. Entries by any method other than set forth above in Section 3 are void. Any use of automated or programmed methods of effecting Entry is prohibited.
Open only to persons, who are, as of Entry, not minors as defined by their state, province or territory of primary residence ("Minors"), and who are legal residents of, and physically located within, the 50 United States, D.C. or Canada (excluding Quebec) (collectively, "Territory"), and are not employees of Sponsor, 3Ci or Administrator; their respective parent, subsidiary or affiliated companies; or the advertising, promotional or fulfillment agencies of any of them (individually and collectively, "Entities"); nor members of their households or immediate families (defined as parents, children, siblings, step-parents, step-children, step-siblings and their spouses).
