Tom Thumb also bought the gourmet specialty Simon David stores in 1963.

Hypermart USA stores were the early, smaller prototype for the current Walmart Supercenter concept.

Their initial lack of success led Tom Thumb to exit the partnership in 1991.

In January 1989, Cullum Companies sold six of its Tom Thumb stores in Austin to Albertsons.

Safeway retained the Randalls name in Houston and Austin and the Tom Thumb name in Dallas/Fort Worth but replaced many of the Tom Thumb/Randalls "Remarkable" and President's Choice store brands with Safeway private label items.

Safeway said the move would revitalize the Texas division and that it planned to remodel stores to fit its "Lifestyle" format and introduce proprietary products.

The new Lifestyle format features an expanded selection of perishables and a number of unique[citation needed] offerings, including a large selection of natural and organic foods, full-service meat counters, full-service bakeries and floral design centers, as well as sushi bars and olive bars.

Lifestyle stores carry an expanded selection of finer foods, ready-to-eat meals, and have a more upscale decor.
