Why not? As long as it's not deceptive, seems ok to me. Trademarks don't mean absolute ownership of a word.

I'm not a huge fan of advertising in retail, but even in offline retail, manufacturers/distributors are paying for shelf space, either directly in dollars or offset from the product cost / managed through other terms. Having your product accessory or competitor shelved nearby a more well known product is helpful; ads in a retail website are analogous to that.
