CHAPTER 2 ■ WHERE TO OBTAIN TOOLS AND PARTS
When purchasing inexpensive components, think about purchasing in quantities larger than you need
for a single project. In quantities of 100, many components are half the price of a single piece (see Figure 2-2).
Some components cost so little (such as resistors) that they often aren’t available in quantities fewer than 10.
Consider informally organizing a group to buy a larger quantity of a particular item. Not only will each
individual lower the unit cost of their parts, but also the group splits the shipping costs.
I try to support my local hardware and hobby stores so that they will be there when I need them. There
are some items, such tools and body materials, that are better to examine in person.
Most online companies offer better prices than retail stores because the stock is consolidated and is
warehoused at a few low-rent locations. Since customers aren’t walking through the aisles, the products can
be stored more densely and needn’t be packaged attractively.
Watch out for minimum order amounts. Most online companies charge a handling fee below a certain
total order size. The minimum order size is often $20 to $25. Also, consider the cost of shipping. It tends to
have a significant base price that grows relatively slowly with weight.
In summary, by consolidating smaller orders into a single purchase and by buying in larger quantities,
the per-unit price of components can be dramatically reduced. Simply plan ahead or combine orders with
friends or local club members.
