Debt Disclosure [Abstract]
Debt	4. Debt At October 28, 2017 and January 28, 2017, we had two unsecured credit facilities; one which allows for borrowings up to $30.0 million with an interest rate at one month LIBOR plus 2.0% and one which allows for borrowings up to $50.0 million at a rate agreed upon between lender and borrower at the time loan is made. Both facilities expire in November 2017. Under the provisions of both facilities, we do not pay commitment fees and are not subject to covenant requirements. At October 28, 2017, a total of $80.0 million was available to us from these facilities. We did not incur any borrowings against our credit facilities during the thirteen week period ended October 28, 2017. There were 7 days during the thirty-nine weeks ended October 28, 2017, where we incurred borrowings against our credit facilities for an average and maximum borrowing of $4.2 million and $4.9 million, respectively, and an average interest rate of 2.8%. There were 19 days during the fifty-two weeks ended January 28, 2017, where we incurred borrowings against our credit facilities for an average and maximum borrowing of $6.6 million and $11.8 million, respectively, and an average interest rate of 2.5%. Subsequent to October 28, 2017, we renewed and amended our $50.0 million facility which now allows for borrowings up to $30.0 million at a rate agreed upon between lender and borrower at the time loan is made. The renewal was effective November 17, 2017 and will expire on March 31, 2018. We also renewed our $30.0 million facility with an interest rate at one month LIBOR plus 2.5%.
