I ordered 3.5 G of shrooms from SW_Psychedelics about a month ago for $15, I see his price is $29 now but I would still order from him/her again. The order was marked shipped within 6 hours and 3 business days later I received via USPS. Stealth was OK but not great, so if that is a huge priority for you keep in mind, but I thought it was perfectly reasonable.
Just two days ago I tried the product and wow did I trip balls, but I took a large dose and it is shrooms after all, so not unexpected.
TL/DR; SW_Psychedelics has reasonable prices, ships fast, has reasonable stealth, and the product is legit.
$30 an eighth is nuts, I usually see them on markets for less than 20. Although locally an eighth of shrooms is half a bill... and people pay that, too. Insane.
