Shopping through the internet

I need envelopes to send my books to customers. Each envelope (A5 size) cost 26 cents from a stationary shop.

As I needed a large number of envelopes, I searched the internet for a manufacturer to supply in bulk. I found an internet-based stationery who offered the envelopes at 8 cents, i.e. about 1/3rd of the retail price. I bought the envelopes and other stationary items for my office through this source, and paid using Paypal.

Lesson: It is easy to do "shopping" through the internet and find out the best source.
