The 50% off Gift Cards sale will be for group members only, as a thank you for your continued support. Some hairstyles will give 50% back to wearer of the Hair SL group, which is a dear promotion partner. There will be areas with different signage and group join posters in the store so you easily see for which vendor you need which group to receive the 50% cash back from your purchase.
There is also an unspecified large number of "general" 99 L Sale items around the store, for which you do not need a group title to buy them at the reduced price.
Flash Mob Vendors will add to the fun :-)
Here your link to the mainstore, come enjoy:
