Sorry for all the questions but I figure this is the best place to aks with all these savvy women  I bought two of those 25 lb bags of sugar last week when they were on sale last week at buy-low. What's the best way to store 50 lbs of sugar? There's only two of us so I'm thinking it will last around 3 yrs. Canning it seems silly for so short a time.. Is a 5 gallon bucket my best option? Can I put sugar in a PETE bottles and use oxygen packets?I have a few used plastic containers that have the PETE symbol and wanted to use those.. ideas suggestions TIA!!!

If you are going to store sugar in a 5 gal bucket w/ a gamma lid, any idea how long it will last and if I should put an oxygen absorber in it?

Here is when Oxygen Absorbers should be used (from providentliving.org)

Oxygen absorbers protect dry foods from insect damage and help preserve product quality. They are used when dry foods are packaged in sealed containers. Oxygen absorbers can be purchased from home storage centers and Church Distribution Services, or they can be ordered from ldscatalog.com.
What are oxygen absorbers made of?
Oxygen absorbers are small packets that contain an iron powder. The packets are made of a material that allows oxygen and moisture to enter but does not allow the iron powder to leak out.
How do oxygen absorbers work?
Moisture in the packaged food causes the iron in the oxygen absorber to rust. As it oxidizes, the iron absorbs oxygen. Oxygen absorbers rated for 300 cubic centimeters (cc) of oxygen work well for properly packaged dry food in containers of up to one-gallon capacity (4 liters).
Is the use of oxygen absorbers equivalent to vacuum packaging?
Oxygen absorbers remove oxygen more effectively than vacuum packaging. Air is about 20 percent oxygen and 80 percent nitrogen. Absorbers remove only the oxygen. The air left in the container is mostly nitrogen and will not affect the food or allow the growth of insects.
What types of products can be stored using oxygen absorbers?
Products should be low in moisture and oil content. If the moisture content is not low enough (about 10 percent or less), storing products in reduced oxygen packaging may result in botulism poisoning. Visit providentliving.org for specific product recommendations.
What types of containers can be used with oxygen absorbers for food storage?
Oxygen absorbers should be used with containers that provide an effective barrier against moisture and oxygen. The following containers work well:
? Metal cans with seamed lids.
? Foil pouches (such as those provided by Church home storage centers and available from ldscatalog.org).
? PETE plastic bottles with airtight, screw-on lids.
? Glass canning jars with metal lids that have gaskets.
Oxygen absorbers are not an effective treatment method for plastic buckets, milk bottles, or other types of plastic bottles not identified as PETE or PET under the recycle symbol (see right).
What is the proper way to use oxygen absorbers?
1. Cut open the top of the bag of absorbers. Do not open the individual absorber packets.
2. Spread out on a tray the number of absorbers that you will use in the next 20 to 30 minutes.
3. Reseal the remaining supply of absorbers by one of the following methods.
? Seal the bag of absorbers with the special blue clamp provided by the home storage center.
? Seal the bag of absorbers with an impulse heat sealer.
? Place the remaining absorbers into a glass canning jar that has a metal lid with a gasket. A one-pint jar (500 ml) will hold 25 absorbers.
Note: Do not store absorbers in zip-lock bags.
4. Place one absorber into each container of food as it is packaged.
5. Remove additional absorbers from the supply, as needed, during the packaging process. Do not open and close the bag repeatedly to get only a few absorbers at a time.
