MLM annoyance

Not sure what to do in this situation.

My husband runs a business and one of his clients is a really nice guy and his wife is also super sweet.

I got a message from her a while ago and surprise surprise shes a brand rep for a workout clothes company.

She’s always been kind and her husband is very supportive of our business, so I ordered a pair of leggings from her and that was it.

Well now she’s added me to this group chat with 10 women and she messages us about 10-15 times a day about deals, new products, and how to do a party. The clothes are not cheap and I could barely afford the leggings I did buy, let alone more from her.

I want to leave the group chat and block her messages, but I don’t want to offend her and potentially have my husband lose a client.

What should I do?
