Received a perfect bunch!
Some things are truly hit or miss with Amazon Fresh grocery deliveries! I Some things are truly hit or miss with Amazon Fresh grocery deliveries! I hadn’t ordered bananas for about a month due to what I’d received in the past. Personal preference? I want those lovely pale green ends! Please!!! I don’t like the flavor or even the change in scent that happens when bananas turn darker yellow, freckle - or worse? Turn brown. Yuck. Each previous delivery, I hadn’t been able to eat more than 3 out of each bunch because of the already yellowed fruit received. I even tried the currently trendy recommendation of wrapping the individual stem ends in plastic wrap to help slow the ripening process. Was very pleased to receive a bunch of 6 small sized bananas, all delicately green and completely beautiful! Beautiful job by the thoughtful delivery person as well, who didn’t just leave the bags in the rain on the (only 2!) steps, but made sure they were under the protection of the porch and not blocking my door. Some items I never order anymore (beloved snap peas and garnet potatoes are two examples) after receiving spoiled items - more than once. Apparently notifying Amazon of our understandable disappointment, not to mention the waste! can sometimes improve the quality of items delivered.

Great mix of Celsius flavors.
Flavor Name: Assorted Flavor Variety, Size: 12 Fl Oz (Pack of 12)
On average, I drink a Celsius a day. Most flavors are pretty good. I like the variability in this assortment. Hence the reason I have this set up on auto order ever few weeks.

Cola flavor is a NO
Flavor Name: Assorted Flavor Variety, Size: 12 Fl Oz (Pack of 12)
I am on a subscription for Celsius. The variety pack gets changed up every so often so it’s nice to try different flavors and exciting to see what I got in my latest shipments. For those bummed out because “Cola” was not included, don’t be. This is a throw away for me. Was hoping for a Diet Coke taste, but it’s not. It’s vile. All other flavors are great, tons of energy before the gym without jitters , low calorie, and I like the amount of carbonation, I think it’s perfect.
