On the contrary: Just because a website doesn't look good, doesn't make it bad. To me, the website presents all the information it needs to: the products they stock, their price and where to get them.
Not every business wants to become internet only. Or, for that note, even have a website in the first place. There are plenty of perfectly profitable businesses that don't. Both staff and customers often value the human interactions a physical store brings. They may make more money with a "half-decent web presence" (might not!) but their business will be reduced to one of simple order fulfilment and lose the what makes running the business enjoyable in the first place. Fabricland has a shop in the town we live. My (non internet using) wife goes there often and appreciates their great service. If they went internet only she would lose this and have to go elsewhere, though I don't know where.
By the way, for your housemate, ordering instructions are there on the front page: "TO ORDER PLEASE CALL US WITH YOUR CREDIT/ SWITCH/ DEBIT CARD DETAILS, WE ARE WAITING TO TAKE YOUR CALL! [...] NO SHOPPING BASKET, JUST CALL PLEASE" It's not as convenient as clicking an item into your shopping basket and paying by paypal, granted, but it's not too difficult either (though does involve talking to someone).
