FreeShipping was started to tackle one very specific issue, and you can probably guess which it is: the annoying delivery costs you encounter when shopping online.
The site has now expanded, so they offer a multitude of other benefits as well as free shipping offers.
These include 10% cashback on purchases at major retailers, 20% cashback during seasonal periods, free return shipping, and price protection if you find the same item sold for less elsewhere.
This is another site that you have to pay membership to join, but you can at least give it a go with the 7-day trial for $2 (the usual price is $13 a month).
If you have a change of heart after paying membership, you can receive a full refund within the first 30 days.
