Post Office investment for lump sum

Hi All
Please advise on the pros & cons of a lumpsum investment in the post office
Also what is the difference between Savings Certificate and Savings Bonds

This is already covered - do a search for thread 'saving bonds v saving certs.' In a nutshell certs are a 5.5 saving term and bonds a 3 year saving term. The terms and conditions for certs are slightly better but both are fully guaranteed, DIRT free and good value at the moment if left for the full term.

This previous post by oldtimer is particularly informative with regard to the differences between certs and bonds.

Always go for the Certs.The interest goes on every six months and if you take them out after three years you are no worse off than if you had them in bonds- but you have the option of leaving them in for another two and a half years. If they were bonds you would have to re invest and the rates may not be as attractive in three years' time.You can dip into or withdraw all your money fron Certs and Bonds at any time with no charge or penalty.If you dip in the amount will be made up of mostly the original capital and then some interest earned.You can't have more than €120,000 in any one issue of Certs in your own name (€240,000 in joint names) but that's per issue not in Certs themselves.So each time the rates change you can buy another €120,000 for the new issue!No DIRT is payable because you are giving the money to the government anyway for the five and a half years.
