While your efforts to boycott seem to be coming from a righteous cause, the effects of your actions are only effecting you. Sometimes thats enough, but the question is are you satisfied with that being the result. You can continue to go without and keep a clear conscious while everyone else enjoys the convenience of service or you could reevaluate your mission and find another way to make a difference. While I applaud your strong will, efforts, and ability to go against the grain, I also disagree with the one of your motives to boycott in the first place. You said that the work is "body-crushing" as far as warehouse work goes. And I dont know if you ever worked in the Amazon warehouse or any warehouse at all but sometimes during some periods of the year thats just what warehouse work could be considered "body crushing".
I'm here to share that I have worked in a number of warehouses and I am currently working in a Amazon warehouse, during the toughest time of year, and I wont call this work body crushing, although it can be tough for some that may not be use to working in a warehouse. It to me is definitely a lot easier than some of the other warehouse jobs I have worked in my days
