eBay have just sent out details of a new sale that covers some LEGO listings.
From today (November 7th) until 11:59 AEDT on November 16th you can get 20% off at selected eBay stores with the code PREZZY.
Looking through the search results it appears to be mainly items listed by Hobby Warehouse, although there are some others in there too.
Don’t forget that with eBay you have to be particularly careful with prices, as they can be higher than RRP.
This link should have all of the LEGO listings covered by the code.
