I haven't used instacart yet, but have used GG for like 6 years. It's my understanding that instacart is pretty new to the area, so it doesn't have the following yet. Also I don't think they deliver alcohol, while GG does (not positive - I could be wrong in remembering that). And, in my researching, the GG deliveries use paper bags, labeled for cold storage if needed, and the instacart seemed to just have plastic bag delivery and wasn't marked the same? I stuck with GG on my last trip, but will look at my options again before my upcoming trip. (Also looked at wegoshop, Dizzy Dolphin, and safeway delivery [the safeway was pretty darn far away from the resort, so i didn't go with that]). Instacart is starting up in my area this month, so I might be more familiar with the company and more willing to try it. Paying $7 for a container of strawberries hurt but they are my kid's favorite, and I won't bring myself to pay $3.29 for an avocado - both on garden grocer.Just wondering why Garden Grocer is so popular when it appears to me that Publix Instacart is so much cheaper with possibly more options. Never used either but want to this coming trip. Anyone who has used both care to comment?
