Clean your trunk out! It may sound silly, but you never know what amazing deals you can find! You are likely to find a large item at an awesome price that you cannot walk away from! So, you want to prepare ahead of time to make sure you have the space to bring it home!!
Measure the inseam of a pair of your child's pants that fit well. Then write the measurement on the itemized list (see last week's tip) next to the pants. Sizes vary so much from one brand to another, so this will help you buy only the pants that look nice AND will be a good fit for your child!
Make a list of what your kids need! Shopping at consignment sales can be overwhelming, so having a specific list that you can check off items as you find them is very helpful!
