I use to offer different packages for senior, family, etc, but it was to complicated, now I just have one set of packages.
My main tip is offer everything, let them know about it, and youll be surprised how many go for the upgrades. I just sold a $1200 package because I offered stuff, and had examples to show. I never really thought I would sell that package but it had everything they wanted, after a couple substitutions.
I dont force them to get x number of 8x10's or wallets, I just offer them sheets, one pose per sheet, then they pick what they want, 8x10's, 5x7's, etc.
Also all my packages include an hour of photography, for those that do a reorder or order multiple packages, they save $50 after the first one, I dont want to double charge them.
My first package is simple, 4 sheets of prints for $150.
My second package is almost as simple, 9 sheets of prints and 40 rep cards for $300.
and so on. Then in my a la carte list I have everything, $35 for a sheet, $100 for a set of 40 rep cards, $100 for 40 grad cards, $400 for a press printed album with 20 pages/20 pictures, $125 for a 11x14, $150 for a storyboard design *plus the cost of the wall print*, etc.
The more you offer, the more they may buy.
I sometimes toss in a freebie or so for good paying customers and hardship cases. Usually something that promotes my business as well, like the rep cards. All depends on my profit margin and how im doing that month.
