Macho Merch is a men-only shopping mall in Rughster Bay, and a few of the vendors here have free items on offer.

First up, the mall itself has 2 promo t-shirts, in Red or Grey. The grey one is shown here, they’re on opposite sides of the main tp point.

Next, “It’s A Guy Thing” has a bag of freebie shirts, and another shirt on the wall which are free. The freebie bag includes fan shirts for New England Patriots, and Aerosmith.

Finally at YJ’s there’s a set on offer that includes a silver ring, and an arm tattoo (undershirt layer only). YJ’s also has some multipack t-shirts and vests that probably count as costing L$1 or less each. The packs cost L$5, and contain 6 shirts each, different colours. I didn’t actually buy any of these, but I did take a snapshot of the boards on the wall to give you an idea.

While I’m on the subject of malls, here’s a little tip. It’s notoriously difficult to find items you want in a mall. If you use the Release Candidate viewer, so that the new Search All works, there’s an easy way. First pull up the search page for the mall (you can type the mall’s name in search to find it easier). Now on that page will be a list of all items offered for sale, along with their price (usually). Scroll down the page, find the items listed free, and make a note of the co-ordinates of that item.
Now open up your map and click on it, using trial-and-error, until you click on or near to the co-ordinates you noted for the free item. Those co-ordinates will be displayed in the panel to the right of the map. When you’ve got the right spot, close the map and now you’ll have a big red beacon marking the location you’re looking for. Your free item will be somewhere close to that beacon. To make the trial and error a little easier, the first co-ordinate runs west-to-east (zero at west) and the second one from south-to-north (zero at south).
Total cost (of items modelled) L$0
