Personal Shopper Catalogue

Why would you buy monthly from stores like SAMS, BJ’S, or Walmart versus Catalog Shopping for the same goods?
Some people I have spoken to and surveyed have concerns about shopping online or through catalogs when they need to buy cleaning products, vitamins, and personal care items that cost much less than shopping at the large grocery stores like Sam’s, Walmart, and BJ’s. I am a loyalty shopper of catalog shopping from a great wellness manufacturing company that researches, develops, and distribute directly to the customer. I get everything I need except for meats and food products and I am saving alot of money monthly instead of shopping at the local grocery store. Plus they send me a thank you check when I refer customers and those customers open an account with the store. All my products are safer for the home and clean better than the dollar store brands so what’s your opinion would you be a regular store shopper and waste money and not get a check or a regular catalog online shopper and get a thank you check no matter how much the amount is?
it’s about psychology. But I think that in the long time people will go for online stuff, when there is convenience
