I bought a box of those (and of Oriental Jasmine) last year just before Christmas; as a gift for myself and also the price seemed quite fair.
I have tried Lavender Grey twice, yesterday for first time, today for second time; sadly both results are not so great. They have used pyramid sachets (in outer wrapping, well that was another reason for buying), but tea itself isn’t really top quality, rather it was a bit dusty and very broken, hardly to see any lavender buds there and in smell it was some generic “Earl Grey aroma” instead of fresh and distinct bergamot.
Sadly, when brewed it’s not much better. Tea base is fine, Ceylon with its bright citrusy notes, no astringency or bitterness, but somehow flat. Bergamot made me feel again that some cheap bergamot oil was used as it was again somehow mediocre and flat. And lavender? Well, in first session I haven’t noticed any, in second session it was just a bit of floral extra note… but I wouldn’t guess a lavender if it wasn’t labeled as such.
