[header] How to write a home improvement contract [title] Define what you want to do. [step] You can't write a good contract unless you can define exactly what you want to accomplish.

Thrift stores and garage sales often sell items that have only been used minimally. <sep> (A) As a result, you may have to collect stuff that's well on sale now and in a way that doesn't cost nearly as much. Be prepared for a general sense of order if you have toys, furniture, books, trinkets and other items you have no storage for.
