I have a blog Zero Waste and one of the reasons for starting that blog is that I hate waste. And here is an online merchant golf balls which are exactly my kind of online merchants, one which do not waste good, usable, used golf balls. Plus one will not waste any money purchasing usable used golf balls from there for they sell golf balls from as low as $1 each. And if you can arrange for bulk purchase, such as by ganging up with your golfing buddies, you can even go for, not only budget golf balls at $1 each, but cheap golf balls at only $0.30 each!!!
Golf balls are not the only golfing necessities you can get from that interesting site. You can also get cheap golf bags. Why waste money lugging around an expensive brand new golf bag when a perfectly usable cheap, used golf bag will do, for after all, both can do the job it is meant to do. That is, carry your golf clubs and other accessories around the golf courses.
Don't know about you, but I wouldn't waste my money on expensive, brand new stuff when cheap and perfectly usable alternatives are available.

Sudoku Puzzle Solving for Recreation
What is Sudoku?
Sudoku is a logic-based number placement puzzle which started its life as "Number Place" invented by an American architect, Howard Garns, in 1979. It was first published by Dell Magazines. The puzzle became very popular in Japan after it was published by the Japanese puzzle giant Nikoli Inc. which renamed the puzzle "Sudoku".The Japanese word "Su" means number and "Doku" refers to the single place on the puzzle board that each number can fit into. The word "Sudoku" also conveys an impression of a person who is single and perhaps probably correspond to "Solitaire". So it will not give it an English name "Solitaire with numbers." Many people also misspelled it as "Soduko" or "Sudoko."
Its international popularity should probably be attributed to a retired Hong Kong judge originally from New Zealand, Wayne Gould. Wayne Gould took years to developed a computer program to generate infinite number of combinations of the puzzle. He then managed to persuade The Times newspaper in London to publish it as a daily puzzle, first on 12th November, 2004.. Many newspapers later followed The Times newspaper's footstep to publish Sudoku puzzle as a leisurely diversion from serious reading. It is now published daily in newspapers and magazines worldwide and many books have been published on strategies to solve the puzzle, etc.
