In 1945 this humble building became the first retail outlet of what is now a worldwide multinational company, whose sales volume in their market is the largest in the world. This company has always had a more extensive product line than any of their competitors, which accounts for much of its success. The company's founders also introduced franchising as their business model, a new concept at the time. Most of all, though, everyone loves their products, and they will always give you some for free if you ask.
The clue at WP1 is written on the back of a street sign, in an ancient language that almost everyone knows. It is plainly visible and is near eye level. There is some traffic, but if you scope it out well you can "grab" it on a casual walk by. Look out for the nearby restaurant owner, who constantly goes outside to smoke. Once you figure out the name of the company from the clue, proceed to their retail outlet that is CLOSEST to WP1. While you are there consider asking for a free sample of one or more of their products (optional).
To log your find, stand at the front door. Remember the number of products you chose from? Proceed that many thousandths of a minute of latitude directly north. For example if you are at N 34° 15.100' and there are 98 products, then proceed to N 34° 15.198' . The cache container is in the obvious structure.
The cache container is a cammoed Altoids tin and an easy grab in spite of the busy area. Please be cautious when reaching for it. Try to include in the log book the name of the product you received, if any- maybe we'll get some too. Leave the cache location as securely closed as you can or at least appearing so, with the "latch" secured just enough to discourage muggles.
