Opinion on the Financial Statements

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 30, 2024 and April 1, 2023, and the results of its operations and its cash flows for each of the three years in the period ended March 30, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of March 30, 2024, based on criteria established inInternal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 14, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that is material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Inventories – Refer to Note 2 to the financial statements

Critical Audit Matter Description

The Company’s inventories consist primarily of purchased merchandise and are valued at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method (which approximates the first in, first out method) and includes the cost of merchandise and import related costs, including freight, duty and agent commissions. A periodic review of inventories is performed in order to determine if inventories are properly stated at the lower of cost or net realizable value. This adjustment calculation requires the Company to make assumptions and estimates, which are

based on factors such as average selling cycle and seasonality of merchandise, the historical rate at which merchandise has sold below cost during the average selling cycle, and the value and nature of merchandise currently priced below original cost. A provision is recorded to reduce the cost of inventories to the estimated net realizable values, if appropriate.

Given the judgments made by management to estimate the net realizable value of inventories, such as estimating future sales prices and foreseeable demand, auditing the adjustments to inventories for obsolescence involved a higher degree of auditor judgment and the involvement of more senior members of the engagement team in executing, supervising, and reviewing the results of the procedures.
