I will probably buy more soon also.
Waiting for the blue light special.
Might have to reneg on the 30 to 40 cents however. Just did a SWAG, went to the TSP site, went back the number of years that I still have to retire, and wow, the I Fund really went up in that time span. I doubt it could drop that much, but who knows. Less than 5 years here, and since I dropped my investments to matching only, wouldn't mind making more than 3 or 4 cents a month the G fund is offering. Tried the F, barely got out ahead. C is out of the question. Small caps, well, depends on the next administration, and even if they do a stellar job, doubt California home prices will recover in 5 years (my other investment, might be even now, depends on the "buyer"). It's up to those across the Atlantic (and the input asia has) to carry us I fund believers into retirement (IMHO). Since I can't really afford to buy gold (not that I'd want to) the fiancee is going to let me "buy" her Euros when she gets here for holiday in July (avoiding exchange fees and such). I'd just as soon sit on that as anything else at this point since I'll be back over there before she can finally move here for good.
The excess that was going into the TSP, so far this year, has been invested into landscape trees. Figure it's about a 3 year investment, and kept the start up cost down to figure a 100% return. People that live in the desert like trees, especially ones that are already 6 foot tall. The tax benefits are not so bad either, but it is a lot of work. The Navy, city and builders (due to BRAC) are always looking for tid bits to decorate the SES's homes with
The remainder is going into assets, vintage motorcycle parts. Lots of items that haven't been seen in quite some time have become available as owners liquidate. Those are long term 10 to 12 years investments. It's hard to calculate the return, but I just figure it as income after retirement ( or inheritance for my son, which ever comes first).
Cash is getting pretty tight however working it this way. Fuel is cutting into the budget, but am pretty happy with the 26mpg my Cummins 2500 quad long bed got on last weekends 700 mile weekend trip. It beats the hell out of airline offerings

Fuel in Topaz, Nv last weekend was $4.59, cheap by California standards. Being how the trip was to pick up a vintage motorcycle, getting the current 55 cents a mile back works out ok.
As far as food cost goes, my recently graduated son turned me on to GNC products. They have really put some energy back into this 52 two year old, and only cost about $45.00/month. The positive side effect has been appetite is down quite a bit, so smaller, lighter meals and more healthy stuff is going down the gob. Can't hurt to get health conscious this close to retirement.
Anyway, that's my "I" fund investment plan

No one ever said life would be easy.
I'm still about 100 grand short of where I'd like to be in 5 years......
