This location has friendly, professional, knowledgeable staff. It is in a secure, attractive building with a very inviting interior. Watch em weigh orders behind glass, pick their brains about whatâs good and whatâs next in seasonal varieties, or snag a million stickers at the back table! Digital menu boards post current prices, percentages, and availability of their many items and brands â and I love that GreenLight will sell grams, as not all medical shops in STL offer 1g increments. They have a great deal where you get a discount for returning your bags, and every order exits the store in a simple and discreet safety-seal black plastic bag WITHOUT their damn logo on it. Stellar service. I love this place. Weekly visitor. Definitely recommend.
