*The first month’s $10 award will be added to the primary membership account after enrollment and must be used within thirty (30) days from the date of membership enrollment. The following $10 awards per month for months two through six will be added to the primary membership account at the beginning of each month and will expire at the end of each month in which they are issued. Awards which are not used by the end of the month in which they are issued will expire and any balance will be forfeited. This special award offer is separate from the My BJ’s Perks® program and does not alter its terms.
