Packages are good as a starting point. Choosing prints can be overwhelming without them. I have packages that people like quite a bit, and they're encouraged to swap out sizes to make it perfect for them.
Yes, this is what I do. Packages with options.
Most people--especially seniors--will also want to know "what does everyone else get?" They will want to position themselves somewhere among their peers--at, above, or below the average. If you can say, "Most people get this...." it makes their own choices much easier and quicker.
You can also subtly set your average pricing this way by building "good, better, best" packages. If they don't ask "What do most people get?" they will still want to know "good, better, best." Make sure your "good" is still a worthwhile profit.
Set up your packages and options smartly--packaging should be either simpler or more profitable for you--preferrably both--than ala carte. Yes, you can set up packages so that they are less expensive for you to produce while at the same time being less expensive for the client than ala carte.
Some options will naturally be more profitable with some packages than others, and in some cases you may even want to vary the prices of the options.
For instance, an option may be more expensive if added to a lower package; the same item might come standard with a higher package and cheaper if another copy is added to that package.
For another instance, adding options to a lower package to make it equal a higher package should be more expensive than buying the higher package.
