===== Linking the marketplace =====

The general URL is:

  * https://www.geolitho.eu/collection/shop.php

==== Your own offers ====

You will certainly want to draw attention to your offers in forums and on other platforms. In addition to the main marketplace page, you can also link directly to your offers from your collections. All you need is the GUSID of your collection. You can find it when you open the collection, displayed at the top under “International collection ID”. Simply append this 22-character alphanumeric string to the following URL:
https://www.geolitho.eu/collection/shop.php?v=

Example: if your unique ID is “GpwiPdyHZ0G5gP3Tj8L25A-g”, the result will be:
  * https://www.geolitho.eu/collection/shop.php?v=GpwiPdyHZ0G5gP3Tj8L25A-g
Using this URL, you can access your offers directly.
