CY2021	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to, the useful lives of property and equipment and intangibles, allowance for sales returns, allowance for bad debts, breakage on loyalty points and rewards, valuation of inventory, warrants, stock-based compensation, valuation of right-of-use assets, valuation of goodwill and acquired intangibles and income taxes.

CY2021	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, marketable securities and accounts receivable. The Company deposits cash at major financial institutions, and at times, such cash may exceed federally insured limits. The credit risk is believed to be minimal due to the financial position of the depository institutions in which those deposits are held. The Company has never experienced any losses on deposits since inception. The Company’s investment policy restricts cash investments to highly liquid, short to intermediate-term, high grade fixed income securities, and as a result, the Company believes its cash equivalents and marketable securities represent minimal credit risk.
