The most costly, time-consuming, and complex interactions are the ones where vendors either have a significant presence in your neighborhood, or the products they sell are in your home. For example, if you have a large home with many appliances, it makes sense to consider doing a deal where each appliance is delivered to your home for free, but there is a fee for the delivery of the products.
Another potentially expensive interaction is when you have to have the products delivered to you and have them delivered to someone else. That means you need someone else to handle the delivery of the products.
If you have a large, densely-populated area, the most expensive interaction is when you’re in the middle of a delivery of products to your home. If you are in the middle of an interaction where you have to give the products to others, you are most likely to take a hit on the amount of your inventory.
If you’re going to buy something from a vendor, you want to be able to buy it from that vendor. If you’ve got a large, densely-populated area, the most expensive interaction would be when you’re in the middle of an interaction where you have to deliver the products to a warehouse. If you’re in the middle of an interaction where you have to give the products to others, you are most likely to take a hit on your inventory.
In general, vendors are an easy item to drop on your inventory. So its not like you would want to take on a large amount of inventory just for the sake of being able to drop it. You probably want to make sure you spend your money on the items you need before you spend even more for items you dont need.
If you can find a vendor’s warehouse (or even one that you can actually go in and look for), you can drop your item in and out of it. If you can find a vendor you can drop in and out of some of his or her inventory to make sure there is no inventory left to sell.
