Sugarpill* (affiliate link) tends to be a brand that's a creature of habit, they usually only hold a sale in February for their birthday and in November for Black Friday. For one day only (until May 8th 12am PST), they're deviating from their habit to hold a "Not A Holiday Sale" for 20% off their pressed and loose eyeshadows (excluding the palettes and trios!)
My favorite picks from the brand are Goldilux (loose), Flamepoint (pressed), and Love+ (pressed).
Are you thinking about picking something up from the sale?
