Fiscal Period, Policy [Policy Text Block]	Fiscal Periods Our fiscal year ends on the Saturday nearest to January 31, which results in fiscal years consisting of 52 or 53 weeks. Unless otherwise stated, references to years in this report relate to fiscal years rather than calendar years. Fiscal year 2021 (“2021”) is comprised of the 52 weeks that began on January 31, 2021 and will end on January 29, 2022. Fiscal year 2020 (“2020”) was comprised of the 52 weeks that began on February 2, 2020 and ended on January 30, 2021. The fiscal quarters ended May 1, 2021 (“first quarter of 2021”) and May 2, 2020 (“first quarter of 2020”) were both comprised of 13 weeks.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling and Administrative Expenses Selling and administrative expenses include store expenses (such as payroll and occupancy costs) and costs related to warehousing (which includes rent), distribution, outbound transportation to our stores, advertising, purchasing, insurance, non-income taxes, accepting credit/debit cards, and overhead. Our selling and administrative expense rates may not be comparable to those of other retailers that include warehousing, distribution, and outbound transportation costs in cost of sales. Warehousing, distribution, and outbound transportation costs included in selling and administrative expenses were $66.2 million and $52.3 million for the first quarter of 2021 and the first quarter of 2020, respectively.

Advertising expenses are included in selling and administrative expenses.

Comparability of Prior Year Financial Data, Policy [Policy Text Block]	Reclassifications In the first quarter of 2021, we realigned select merchandise categories to be consistent with the initial realignment of our merchandising team and changes to our management reporting. We eliminated our Electronics, Toys, & Accessories category by absorbing its former merchandise departments into three of our existing merchandise categories. We moved our apparel, jewelry, and hosiery departments into our Soft Home merchandise category, our toys department into our Seasonal merchandise category, and our electronics department into our Hard Home merchandise category. Our six merchandise categories, which match our internal management and reporting of merchandise net sales are now as follows: Food; Consumables; Soft Home; Hard Home; Furniture; and Seasonal. The Food category includes our beverage & grocery; candy & snacks; and specialty foods departments. The Consumables category includes our health, beauty and cosmetics; plastics; paper; chemical; and pet departments. The Soft Home category includes our home décor; frames; fashion bedding; utility bedding; bath; window; decorative textile; home organization; area rugs; apparel; hosiery; and jewelry departments. The Hard Home category includes our small appliances; table top; food preparation; stationery; home maintenance; and electronics departments. The Furniture category includes our upholstery; mattress; ready-to-assemble; and case goods departments. The Seasonal category includes our lawn & garden; summer; Christmas; toys; and other holiday departments. In order to provide comparative information, we have reclassified our results into the new alignment for both periods presented.
