Here is a contact number for Sterilite head sales office:
1-800-225-1046
Make contact with them and give them the model number you are after. Then they will ask for your zip and tell you what stores they supply in your area. If they do not find any in your state ask them to do a US wide search and they will give you the largest companies they supply and then you'll have to look them up seperately.
Keep in mind that the 2 ladies that answer the phone are easily aggitated and have probably been doing the same job for 60 years. They will hang up on you if you've no patience. 
I use the 1986LAB8 models that are 40 Qt and have the lockable handle that pulls up over the lid. The best ones out there IMO for the rack system I have. However all the major retailers quit selling them and I had to use the steps above to get in contact with a store on the East Coast that carries them.
Hope this helps,
Jeff & Starr
