Rose Mille review for Point of Sale

I have been using Shopify on-line since 2013, and POS as soon as it came out. In the beginning, they had a free version, but it did not print receipts or have a "Save Cart" feature. So I opted for the paid version of POS. It wasn't much more at the time, but then Shopify combined the paid version as part of the ecommerce site for no extra fee, Yay! (Except Hey, I have been paying for it for a while and now it's free? hmmm) So then they raised the price of the ecommerce, which still included the previous paid POS version. Fine. I was okay with the arrangement. Most of my sales are online, but once a week we are open, like a pop-up. I love the POS system on the ipad, that uses a barcode scanner, printer, and card reader. And for years I used the "Save Cart" feature as customers tend to pile up all the things they want to purchase to keep their hands free. This feature saved the day. Except now they have a Pro Version - For $89 a month extra! As soon as they came out with it, they took away the "Save Cart" feature in the "lite" version, (which was what the version I had was now called). I cannot justify spending $89 more a month for 4 days of sales just so I can save carts while my customers shop. My work around is to have a second ipad so I can at least have 2 carts going at a time. My customers often travel far to be able to purchase in store, and they buy dozens of little items that take a long time to ring up. While they are shopping another customer often comes up to purchase one thing, but we have customer #1's cart going, ugg. So that is when we can use the backup ipad. PLEASE Please Shopify, let me have "Save Cart" back. We only need it on one register, one day a week. I guess it is too much to ask. BTW, I have 3 Shopify sites, doesn't that buy me "Save Cart" for just 1 of them? Or, maybe a fix for my POS?
