endmodule To use the above module, you would instantiate it in your top-level Verilog file or in a testbench. Here’s a simple testbench example:
// Output the product assign product;
multiplier_8bit_manual uut (.a(a), .b(b), .product(product), .start(start), .clk(clk), .reset(reset));
It’s not because we have access to some exclusive deal.
Just like a car manufacturer builds a car and relies on dealers to sell it, software creators develop products and work with retail partners to distribute them.
Major retailers like Best Buy aren’t focused on offering the lowest prices. With many stores, employees, and large overheads, their pricing reflects their operating costs.
To get big-box stores to carry certain software products, developers often provide wholesale discounts of 34% to 40%.
Why? Because once the software is developed and launched, selling each additional copy costs virtually nothing.
It’s similar to when Taylor releases a new album—every extra sale takes zero effort.
Now back to Best Buy.
When a developer offers favorable pricing to one retailer, they’re often required by law to extend the same terms to all authorized resellers.
Including Software Keep.

We Had a Choice
One option was to do what Best Buy does: keep around for ourselves and sell it to you at retail.
But this is silly because we don't have the overheads that Best Buy has. That means we can pass some of those savings to you while maintaining a healthy, equitable business.
So that's what we did. It's why you're seeing a
discount today.
