Needs SD Card

Yesterday my husband was working on his truck and he said he needed to change the fuel pump. I was hesitant to say yes because it was expensive but he said he really needed it to make his truck go. So he went to the parts house to buy it. After the parts house he stop at the electronics store to check their sd card because he saw in the sales paper that it was on sale. I told him do not get any until next week maybe it still on sale. I know that he really needs a new one to use for his camera but it is not important he may buy one next week.
