Well - how large the discount is could be debated.
The regiment packs are supposedly half the price - but that is half the price of the individual models if you bought them in the normal blister packs.
The normal blister packs are usually £12 for infantry and £13 for cavalry I think.
Those blister packs on their ebay site seem to mainly be at £9.00 so around 20% but you need to buy a few to spread the postage cost.
I have always thought Foundry stuff was over priced anyway so only buy when I see it discounted and discounted heavily ............
If you are going to buy then beware the postage - the auctions/buy it now say £4 and extra buys are free, but the site was addding 50p per extra purchase.
I have pointed this out in a telephone call with Neil about 10 hours ago, but not sure if they have corrected it.
