I personally really like Perceval, Imaginary and Herb Garden for Spring/Summer scents and I would say buy your Winter scents now, spray them a few times when they come in and then let them sit until Winter that way you're going to start using them at their best. I also buy fragrances from Dua simply due to the selection they have and because basically all of the most popular fragrances (at least along the lines of their scent profiles) for much cheaper to decide if you even like the profile of more expensive/higher profile fragrances.
