[I hate such a wonderful plan referred to as DRIP!;-) ]
Yes, according to my booklet DRP REPORT - Allstate has a DRP plan, Opt Cash $25-$3000 per month. Opt Cash or div reinvested is prorated Brokerage +5% max or $2.50 min. If you want to sell your DRP shares it is brokerage + 15.00. Usually the brokerage is minimal.
For the last 11 years I have published the DRP REPORT which lists this type of information along with addresses and Direct purchase stocks. If I can be of any more help please feel free to Email me at SAMinTX@tyler.net.
