Why is it so important as to if Trader Joe has Wifi. I go there to shop not be on wifi. If it's about coupons. Get them down loaded before you go

Using WiFi, people can check recipes, get reviews and even look for those coupons. Here's a quote from the article [ Jul. 10, 2018 ]linked at the end of this comment: "Trader Joe's doesn't offer sales, promotions, or coupons, but it does accept manufacturers' coupons for non-private-label products, which can sometimes be found online." https://www.businessinsider.com/trader-joes-shopping-hacks-save-time-and-money-2018-2
