Shipt Deceptive and Possibily Illegal Pricing Birmingham Alabama

I signed up for Shipt after trying Meijer's pick up service. Meijer charged me a fee for the pickup and so I was directed to sign up for Shipt where you pay a membership fee and get free delivery on orders over $35.

I checked the website yesterday and saw in the help section that they mark up the prices. This is the OPPOSITE of what I was told when I signed up. The entire marketing ploy was that you pay the same prices but with the membership fee they do the shopping. 

When I contacted customer service yesterday, they said that the knowledge that they markup is in their website but that is not how they sold it to me. The agent said the markup is to cover their costs and I said "THAT IS WHAT THE MEMBERSHIP FEE WAS SUPPOSED TO BE FOR!".

Also, it is deceptive that they give you "free delivery" on orders over $35. It is not "free" when they still mark up the prices of the items. The membership fee is supposed to cover their costs.

I had them cancel my account and refund the last mark up.

They issued me a $12.78 refund on a $63.69 order, which is a 25% markup! This is a 75% higher markup than the 14% markup stated on their website.

I believe this is deceptive and possibly illegal.  Their actual markups, based on their own information via their refund to me, are 75% higher than quoted on their website.  Additionally, when you sign up as a new user nowhere does it say that the goods are marked up.  You are told that you pay a membership fee to get the service.
