So the parfum muse samples deal is definitely worth it given there's no min spend.
Inside is a billy eilish 2 dabber (7.5ml) 3 x BDK 2ml ( impadia, gris charnel, 312 st honore) about 3 les eaux primordiales, and a selection of 1.5ml elie saab/banana republic/ orabella and some random ones. About 16 in total.
Given that the cheapest thing you can buy to get the deal is around £10, plus postage of £5 it's not bad.
I may or may not have gone mad and bought a few separate cheap things in different transactions!
Also bought the les eaux primordiales discovery set to get the deal, this was a bit more expensive at £25 but has 6 x 2ml in the kit. Tried Vanilla Supermassive - very nice reminds me of gentle fluidity gold.
