But the start of this was someone who was talking about it being free prior to 2021, which likely means he’/she is in the US. The key was that there was a recent change. For those place where things didn’t change it’s not relevant.
Majority of Zavvi customers don't use Zavvi USA website they use Zavvi UK or Zavvi Germany etc
Free shipping with Steelbook for international customers was about 3 years ago after this shipping you had to pay.
Members used a discount code to get free shipping when code worked and only discounted shipping cost by £1.99
Customers based in UK shipping cost is £1.99
So that is why the code only reduces shipping by £1.99
UK based customers lost free shipping on steelbooks with Zavvi UK in August 2019 unless they subscribed to Red Carpet.
Zavvi USA website was not supposed to have free shipping with Steelbooks anyway that was an error.
This why you often see posted in past few years members post any free shipping discount code working.
Free shipping discount code now only works on instock items not pre orders since November 2020.
That code when works only reduces shipping cost by £1.99
International shipping cost varies depending on delivery country address.
Example shipping cost to Republic of Ireland is €4.49
A discount code £1.99(€2.29) when works reduces that to €2.20
Shipping discount code still works but only for instock items not pre orders.
That is what changed in November 2020
