While for many celebrating the Second Life Birthday do so by attending discussions with the Lindens and Moles, going to music parties, and touring the exhibits, for some of us the thing to do is shop. And so there is the "Shop and Hop" event for the SL19B. It's set in twenty sims separate from the main Birthday area, but still in a Steampunk theme, as is the event theme.
This year, you’ll find a record-breaking 400 participating merchants across 20 regions. In addition to deep discounts and deals, there are also exclusive and completely new gifts available for free at all the shops.
You can find SURLs for the hundreds of stores taking part on the page for the event in the Linden blog. Or if you want to just jump right in, here's one place: http://maps.secondlife.com/secondlife/Gleaming/112/111/52
