I like Escentual and have bought from them a lot. I am impressed that although it says 25% off RRP, you do actually get 25% off any offer/discounted prices.
If you like Estée Lauder, particularly the Night Repair, this set is not a bad price. With the 25% off, it is £47, free P&P. *
It’s a 50ml Night Repair, currently £82 + P&P on QVC. Although the other three items are not full size, they would last quite a while (they are the sizes you usually get in gifts with purchase).
* Escentual offer price £62.66 without discount code, RRP £94, stated value £132.
