So, I have been dealing with this company for the past two years thanks to inflation, and generally speaking it's been a positive experience. My only complaint was the long wait time to get paid - they would send me a text saying my check was mailed today and I wouldn't get it for three weeks, despite being the next state over.
This morning, I planned on sending five boxes using this supposedly new UPS Store option with a QR code because they say it's a $10 bonus and faster payment. I clicked the QR code request button, which was supposed to take me to the UPS site to get the code. It didn't. Tried again. And and again. Nothing worked. I tried the live chat on their site, no response. I emailed, it was bounced back. I called the phone number, didn't go through. Then I searched "Cash For Diabetics Florida scam" and found a news report and this site, and now I'm convinced it is definitely something shady.
I gave three stars because I'm a "split the difference" kind of person. They provided free shipping, paid me, the checks always cleared - albeit some of the payments should have been higher. But clearly others here have had a much different experience, so I am steering clear of all of these companies. This might even be an illegal thing to do and I'm too cute for the slammer.
