Loss from package theft from doorsteps is still less than retail shrinkage. It's difficult to get exact numbers, but even in densely populated areas it's unlikely to reach the retail shrinkage of 1.44%.

If package theft decreased from, say...1% to 0.1%, that would not substantially impact price on the micro scale.

That's pretty much a 0.9% reduction on overall costs to the seller. Most credit cards offer 1% cashback and people love it, so I will dare to say that a 1% price reduction is very interesting.
