I used to live in a small town in Cheshire with 8 pharmacies within 4 miles, all along my walking and bus routes - I'd pick up 2 boxes on the way to the bus stop, get off the bus 3 minutes later and get another 3 boxes, jump back on the bus for 20 minutes, pick up another 2 boxes, back on the bus for 5 minutes and then pick up my final box.
It was perfect for my needs. £4 for a daily bus pass, £1.20 per box (on average) meant I had the equivalent of 200mg of Morphine for £13.60.
Is like that here. Three in the same shopping centre and then two supermarket pharmacies, all on bus route so one day rider for three quid and then however much the codeine costs. Fuck I might do that today actually.
I had some...not last week, week before, and it seemed no matter how many different filters I used, it just kept getting clouded up. Ended up binning half of it and just drinking what was clear or close to clear because fuck spending four hours on an extraction. Before that I'd managed perfect one in about two hours from grinding the tabs up to drinking it. Stuff really is hit or miss with me but definitely a good idea to spread the filtering across a few different glasses. More washing up but hey.
